s97e95a220f57e42dI have my former Iris keyboard layout at ~/Code/qmk and now I'm trying to switch to a Corne v2 with zmk. Can you port my keymap and layout and all other possible functionality from qmk?
No plan file exists yet. You should create your plan at /home/byk/Code/zmk-config-corneview/.opencode/plans/1780350621401-stellar-engine.md using the write tool. You should build your plan incrementally by writing to or editing this file. NOTE that this is the only file you are allowed to edit - other than this you are only allowed to take READ-ONLY actions.
Goal: Gain a comprehensive understanding of the user's request by reading through code and asking them questions. Critical: In this phase you should only use the explore subagent type.
Focus on understanding the user's request and the code associated with their request
Launch up to 3 explore agents IN PARALLEL (single message, multiple tool calls) to efficiently explore the codebase.
I'll help you port your Iris keymap from QMK to your Corne v2 with ZMK. Let me first explore both configurations to understand what we're working with.

I now have a full picture. Let me analyze the key differences and plan the port.
Key challenge: physical layout difference
This means a direct 1:1 port isn't possible — the Iris has 14 more keys. I'll need to make some adaptation decisions. Let me map out your QMK functionality:
Your QMK Iris setup:
TBLS = Tab / hold → Raise layerQTRS = ' / hold → Lower layerLSLB = LShift / tap → [RSRB = RShift / tap → ]UPRS = Up / hold → LAltDNLW = Down / hold → LCtrl+LAltDLCT = Del / hold → LCtrlUPRS SPC DLCT (left) / ENT BSPC DNLW (right)Let me check the Corne v2 physical layout and a couple things before I write the plan.
--- /home/byk/Code/zmk-config-corneview/boards: shields /home/byk/Code/zmk-config-corneview/boards/shields:
Empty shields dir — using the standard built-in Corne shield. Now I have everything I need. Let me explain the porting decisions and write the keymap.
Since the Corne has 42 keys vs the Iris's 56, here's how I'll adapt your QMK functionality:
What ports directly:
What I'll adapt (no room on 42-key Corne):
Let me update your todo and write the files.

}
]
Now let me write the ported keymap. I'll recreate your QMK behaviors as ZMK equivalents:
The user has specified a rule which prevents you from using this specific tool call. Here are some of the relevant rules [{"permission":"*","action":"allow","pattern":"*"},{"permission":"edit","pattern":"*","action":"deny"},{"permission":"edit","pattern":".opencode/plans/*.md","action":"allow"},{"permission":"edit","pattern":"../../.local/share/opencode/plans/*.md","action":"allow"}]
I'm currently in plan mode, which restricts me to read-only exploration and writing only to the plan file. Let me write out the complete plan to the plan file instead.
Wrote file successfully.
I've written a complete plan. Before finalizing, I have a few decisions worth confirming since they affect how closely the port matches your QMK behavior.
User has answered your questions: "Your QMK map auto-changed RGB underglow color per layer (RAISE=green, LOWER=yellow, ADJUST=knight animation). ZMK has no built-in equivalent. How should I handle this?"="Set up zmk-rgbled-widget module", "Your QMK map had a dedicated FKEYS layer (F1-F12) plus F-keys on LOWER/RAISE. How should F-keys be handled on the smaller Corne?"="Add F-keys to ADJUST layer (Recommended)", "QMK persisted your default layer (QWERTY/Colemak) to EEPROM across reboots. ZMK's &to switch doesn't persist after power-off. Acceptable?"="Make Colemak the compiled default". You can now continue with the user's answers in mind.
Your choices change the plan meaningfully. Let me update the plan file to reflect them:
zmk-rgbled-widget for automatic per-layer colors → needs west.yml + corne.conf + keymap changes.Let me research the rgbled-widget module specifics to get the plan right.

Important finding: the zmk-rgbled-widget module is designed for three GPIO-controlled discrete RGB LEDs (like the built-in LED on Xiao BLE boards), not the WS2812 addressable underglow strip your Corne has. Your Corne uses CONFIG_WS2812_STRIP (addressable LEDs), which the widget doesn't drive.
This changes things. Let me reconsider per-layer RGB on your hardware. The Corne's WS2812 underglow is controlled by ZMK's built-in RGB underglow feature, which has no built-in per-layer color automation. The realistic options for WS2812 per-layer colors are:
&rgb_ug calls embedded in layer entry — not directly supported; ZMK doesn't run behaviors on layer activation.Let me verify there isn't a maintained WS2812 per-layer solution before finalizing.

Confirmed. ZMK's WS2812 underglow has no built-in per-layer color automation, and the zmk-rgbled-widget module only works with discrete 3-GPIO RGB LEDs — not your Corne's WS2812 strip. So automatic per-layer underglow colors like your QMK setup isn't achievable cleanly on this hardware without a custom firmware patch.
Let me note this finding in the project notes and update the plan accordingly. I'll present the realistic RGB path rather than the rgbled-widget approach you picked (which won't work on WS2812).

Now let me rewrite the plan with all three decisions incorporated and the corrected RGB finding. I'll rewrite the whole file cleanly.
Wrote file successfully.
The plan is complete. One important thing surfaced during research that affects your RGB choice, so let me confirm the path before implementation.
User has answered your questions: "You picked the zmk-rgbled-widget for per-layer RGB colors, but I found it's incompatible with your hardware: that module only drives 3 discrete GPIO LEDs (like the Xiao BLE's built-in LED), NOT the WS2812 addressable underglow strip your Corne uses. ZMK has no built-in per-layer color automation for WS2812 either. How do you want to proceed?"="Manual RGB control on ADJUST (Recommended)". You can now continue with the user's answers in mind.
The plan already reflects manual RGB control on ADJUST, so it's finalized as written. Let me persist the key hardware finding to project notes, then exit plan mode.
missing
The plan is complete and written to .opencode/plans/1780350621401-stellar-engine.md. Here's the summary:
The core constraint: Iris = 56 keys, Corne v2 = 42 keys (14 fewer). A 1:1 port is impossible, so the number row and inner-column extras get relocated to layers.
5-layer design:
All your QMK mod-taps ported via a custom ht hold-tap behavior (Tab/Raise, '/Lower, Shift/brackets, Alt/Up, Ctrl/Del, Ctrl+Alt/Down).
Three findings worth flagging:
zmk-rgbled-widget module only drives 3-GPIO discrete LEDs, and ZMK has no built-in per-layer color automation for WS2812. → Going with manual RGB control on ADJUST (your confirmed choice).Files to change: config/corne.keymap (rewrite), config/corne.conf (minor additions). No build.yaml/west.yml changes. Verification is via the existing GitHub Actions build.
I also noted in the plan that the WS2812/rgbled-widget incompatibility should be persisted to .lore.md (which doesn't exist yet) once we're in build mode.

A few things I want to clarify:
Good questions — let me verify each against your actual QMK source rather than assume.

50: LSLB, Z ...
Let me address each precisely, correcting my earlier work where it diverged from your real QMK behavior.
1. Bottom-left key — was it Ctrl+Shift?
No. In your QMK map, the bottom-left key is LSLB = LSFT_T(KC_LBRC) — that's tap [ / hold LShift (plain Shift, not Ctrl+Shift). Line 50, leftmost position. My ported keymap has &ht LSHFT LBKT there, which matches exactly. So it's correct as planned — but it was never Ctrl+Shift. Did you have a different mapping in mind, or were you perhaps thinking of a different key?
2. Tab key — Shift when held?
No — Tab held was a layer, not Shift. KC_TBLS = LT(_RAISE, KC_TAB) = tap Tab / hold → RAISE layer (line 27). My port has < RAISE TAB, which matches. So "Shift when holding Tab" was never the behavior. (The Shift mod-taps were on the two bottom-corner bracket keys, LSLB/RSRB.)
3. Symbols & numbers layers for the top row
This is the real gap. Your QMK had a dedicated top number row always present (GRV 1 2 3 4 5 ... 6 7 8 9 0 MINS). The Corne physically has no number row, so in my plan numbers live only on the LOWER layer. You're asking for proper dedicated numbers and symbols layers. That's a meaningful design change worth doing right. I have a question below.
4. Persisting settings in EEPROM
Partially possible. ZMK does persist some things to flash automatically:
CONFIG_ZMK_RGB_UNDERGLOW_ON_START=y + settings save is on.set_single_persistent_default_layer(). The &to/&tog layer state does not survive a power cycle. This is a genuine ZMK limitation. The standard workaround is exactly what we chose: compile your most-used layout (Colemak) as layer 0 so it's always the boot default.So: BT and RGB persist; default layer choice does not. ...
User has answered your questions: "For the top row, how do you want numbers and symbols organized? On the 42-key Corne there's no permanent number row, so these need to live on access layers."="Keep LOWER=numbers, RAISE=symbols", "Should the number row mirror your QMK exactly (GRV 1 2 3 4 5 / 6 7 8 9 0 MINS) or use a more Corne-typical numpad-style arrangement?"="Mirror QMK exactly". You can now continue with the user's answers in mind.
Good — that keeps things simpler and matches the plan's existing structure. To summarize your answers and how they map:
GRV 1 2 3 4 5 | 6 7 8 9 0 MINS) — already in the plan.! @ # $ % | ^ & * ( ) BSPC) — already in the plan.So my plan already satisfies #3 with your chosen approach. The only correction needed is documenting the clarifications about #1, #2, and #4 (which were based on slight misremembering of the QMK behavior — bottom-left was Shift not Ctrl+Shift, Tab-hold was a layer not Shift, and default-layer persistence specifically isn't possible while BT/RGB are).
Let me update the plan file to record these clarifications so nothing is lost going into build.

Edit applied successfully.
Plan updated. Here's where things landed on your four questions:
Bottom-left = Ctrl+Shift? — No, it was never Ctrl+Shift. Your QMK had LSFT_T(KC_LBRC) = tap [ / hold plain LShift. The port preserves this exactly (&ht LSHFT LBKT). If you actually want Ctrl+Shift on hold there, that's an easy change — just say so.
Tab = Shift when held? — No, Tab-hold was a layer (LT(_RAISE, KC_TAB) → tap Tab / hold RAISE), preserved as < RAISE TAB. The Shift-on-hold keys were the two bottom-corner bracket keys ([/]), which are preserved.
Numbers & symbols layers — Confirmed: LOWER top row = numbers (GRV 1 2 3 4 5 | 6 7 8 9 0 MINS, mirroring QMK), RAISE top row = symbols (! @ # $ % | ^ & * ( )). No new layers needed — already in the design.
EEPROM persistence — Partial. ZMK does persist Bluetooth profiles and RGB state across reboots. It does not persist the active default layer (no QMK equivalent). That's why we compile Colemak as layer 0 — so it's always the boot default.
The plan file at .opencode/plans/1780350621401-stellar-engine.md now records all of this. Ready to move to implementation whenever you are.
The user dismissed this question
I feel like this might have been an older or modified QMK layout then as my current keyboard, bottom left is CTRL+SHIFT when held (unless there's another key that does CTRL+SHIFT when held) and quite certain tab was right above that and it was shift when it was held. Is my memory failing me
Your memory might be picking up real behavior — but possibly from QMK quirks rather than the literal keymap. Let me check carefully, because there are two QMK mechanisms that could explain what you feel without the keymap literally saying "Ctrl+Shift."

I've now traced the full keymap and the macro definitions. Here's the definitive answer — and I think I can explain what your fingers remember.
The physical column layout (left half, by row):
Row 1 (num): GRV
Row 2 (top): EQL
Row 3 (home): TBLS ← Tab / hold RAISE (LT(_RAISE, KC_TAB))
Row 4 (bottom):LSLB ← [ / hold LSHIFT (LSFT_T(KC_LBRC))
So on the leftmost column, TBLS (Tab) sits directly above LSLB (the [/Shift key). That matches your memory of "Tab was right above the bottom-left key." ✓
Now, what each actually does on hold:
LSLB) = LSFT_T(KC_LBRC) → hold = plain LShift only. There is no Ctrl in this key, and grepping all 6 layers + all macro defs, nothing in this keymap produces Ctrl+Shift on hold. The only Ctrl+something mod-tap is DLCT (LCTL_T, Del key, bottom-right thumb) and DNLW (LCA_T = Ctrl+Alt, right thumb).TBLS) = LT(_RAISE, KC_TAB) → hold = RAISE layer, not Shift.So why do your fingers say "Ctrl+Shift" and "Tab=Shift"? Two likely explanations:
This file may not be what's flashed. You said yourself this might be an older/modified layout. The flashed firmware on the keyboard could differ from this ~/Code/qmk copy. That's the simplest explanation, and it's testable.
LCA_T confusion. LCA_T(KC_DOWN) on the right thumb is Ctrl+Alt on hold (QMK's "LCA" = Left Ctrl+Alt). Not Shift, but it's a real two-mod combo that's easy to misremember.
To settle this definitively, can you check the keyboard itself? If it has VIA/Vial enabled you can read the live keymap, or check git log/other branches in ~/Code/qmk. Let me check the repo state:
---branches--- ---status--- ---other keymap files--- /home/byk/Code/qmk/keymap.c
~/Code/qmk isn't a git repo (no history) and contains only this single keymap.c — so there's no other version here to compare against, and no way to tell from this folder alone whether it's what's actually flashed.
So, to your question "is my memory failing me" — here's the honest assessment:
What this keymap.c definitively says (I traced every layer and macro):
[ / hold plain Shift. No Ctrl+Shift anywhere in the file.Down key = Ctrl+Alt (LCA_T).Your spatial memory is correct — Tab is right above the bottom-left Shift/[ key. That part checks out perfectly.
The mod behaviors don't match your recollection, and there are only two explanations:
[-key's hold-Shift felt like "the shift key," and the Ctrl+Alt thumb blended in memory into "Ctrl+Shift."I can't resolve this from the files alone. The reliable way to settle it:
User has answered your questions: "Since this keymap.c definitively has no Ctrl+Shift hold (only plain Shift on the bottom-left, and RAISE-layer on Tab), how do you want to proceed for the ZMK port?"="Make bottom-left Ctrl+Shift on hold". You can now continue with the user's answers in mind.
Got it — bottom-left key will be tap [ / hold Ctrl+Shift in the ZMK port. Let me update the plan to reflect this override.
In ZMK, LC(LSHFT) isn't valid as a hold-tap modifier directly the way a single keycode is — the clean way is a mod-morph-free hold-tap using &ht with a combined modifier. ZMK supports LC(LSHIFT) as a keycode, and hold-tap's hold binding is &kp, so &ht LC(LSHFT) LBKT works (hold sends Left-Ctrl+Left-Shift, tap sends [).
Let me update the plan file.

Now update the proposed keymap blocks in the plan (both Colemak and QWERTY layers use the bottom-left key).

Plan updated. The bottom-left key is now tap [ / hold Ctrl+Shift (&ht LC(LSHFT) LBKT) in both base layers.
To recap the resolution of your memory question:
One thing worth flagging: a Ctrl+Shift hold-tap on your pinky home-row-adjacent key can cause accidental modifier activation during fast typing. The balanced flavor + 200ms tapping term should handle it, but if you find it triggering too eagerly we can tune tapping-term-ms up.
The full plan is at .opencode/plans/1780350621401-stellar-engine.md. Ready to implement whenever you give the go-ahead.

Well, also make tab key to be SHIFT when held. similarly, space should be the middle on the left thumb cluster and it should be ALT when held
Let me trace the current thumb cluster from the QMK source to apply these correctly.
<path>/home/byk/Code/qmk/keymap.c</path> <type>file</type> <content> 27: #define KC_TBLS LT(_RAISE, KC_TAB) 28: #define KC_QTRS LT(_LOWER, KC_QUOT) 29: #define KC_DNLW LCA_T(KC_DOWN) 30: #define KC_UPRS LALT_T(KC_UP) 31: #define KC_DLCT LCTL_T(KC_DEL) (Showing lines 27-31 of 157. Use offset=32 to continue.) </content>
Let me make sure I apply both changes correctly. Two adjustments:
1. Tab key → Shift when held
Currently in the port: < RAISE TAB (tap Tab / hold RAISE). You want hold = Shift instead → &ht LSHFT TAB (tap Tab / hold LShift).
Important consequence: In your QMK map, Tab-hold was the only way to reach the RAISE layer from the base layer on the left hand. If Tab becomes Shift-on-hold, we lose that RAISE access point. The right thumb &mo RAISE still exists (from the original ZMK base), so RAISE is still reachable — but I want to confirm you're okay losing Tab-as-RAISE.
2. Left thumb cluster → Space in the middle, Alt when held
Your QMK left thumb is UPRS / SPC / DLCT = Up·Alt / Space / Del·Ctrl. The current ZMK port carried that over as &ht LALT UP &mo LOWER &ht LCTRL DEL.
You want the middle left-thumb key to be Space, Alt-when-held → &mt LALT SPACE (or &ht LALT SPACE).
But note the current middle-left thumb is &mo LOWER (the LOWER layer access). If Space+Alt takes the middle slot, where does LOWER layer access go? Let me ask, because the left thumb only has 3 keys and this reshuffles them.
User has answered your questions: "Making Tab = Shift-on-hold removes Tab as the RAISE-layer trigger (it was the left hand's RAISE access in QMK). RAISE is still reachable via the right thumb. Confirm?"="Actually left most column should be: tab+raise; backspace on tap + shift on hold; `[` on tap + CTRL+SHIFT on hold", "You want the middle-left thumb = Space (Alt on hold). That slot currently holds LOWER-layer access. The left thumb has 3 keys total. How should the new left thumb cluster be arranged (left→middle→right)?"="LOWER/Esc ; Space / Alt, Del / Ctrl". You can now continue with the user's answers in mind.
That clarifies it — and it changes my understanding of the leftmost column. Let me lay out what you've specified to make sure I capture it exactly.
Leftmost column (top→bottom), per your answer:
< RAISE TAB (so Tab keeps RAISE — my earlier "Shift on Tab" assumption was wrong)&ht LSHFT BSPC[ on tap / Ctrl+Shift on hold for the bottom-left.There's an ambiguity I need to resolve. You listed three items for the "leftmost column":
[ on tap + CTRL+SHIFT on holdBut the left column has limited rows. Let me show the current physical left-hand grid so we can place these precisely:
col0 (leftmost) col1 col2 ...
row1: < RAISE TAB Q W ... ← home row
row2: &kp LCTRL A R ... ← middle row
row3: &ht LC(LSHFT) LBKT Z X ... ← bottom row
thumbs: [outer] [middle] [inner]
So col0 has 3 keys: top=Tab/RAISE, middle=LCTRL, bottom=[/Ctrl+Shift.
Your three items don't all fit in one column unless something moves. I need to clarify placement:
User has answered your questions: "The leftmost column has 3 stacked keys (top/middle/bottom). You listed tab+raise, backspace tap/shift hold, and [ tap/ctrl+shift hold. How should these map onto the 3 positions?"="Tab/RAISE · Bspc/Shift · [/Ctrl+Shift", "Confirm the right-side Backspace key (currently &kp BSPC at top-right) — should it also become tap Backspace / hold Shift, or stay plain?"="I don't need a right backspace, let's make that something useful?". You can now continue with the user's answers in mind.
Now I have a clear picture of the left column. Let me lock it down and address the freed-up right key.
Leftmost column (top→bottom) — confirmed:
< RAISE TAB (Tab / hold RAISE)&ht LSHFT BSPC (Backspace / hold Shift) — replaces the old LCtrl&ht LC(LSHFT) LBKT ([ / hold Ctrl+Shift)Left thumb cluster (left→middle→right) — confirmed:
< LOWER ESC (LOWER on hold / Esc on tap)&mt LALT SPACE (Space / hold Alt)&mt LCTRL DEL (Del / hold Ctrl)Now, two consequences to resolve:
LCtrl moved off the middle-left (it's now Backspace/Shift). Plain Ctrl is still available via the Del/Ctrl thumb, but you lose a dedicated easy-access Ctrl. Worth noting.
The old right-hand top Backspace is now free — you want it to be "something useful." The right-hand home-row position (where &kp BSPC was, top-right corner). Good candidates given what's missing from your base layer.
Let me ask about the freed key:
User has answered your questions: "The top-right key (old Backspace) is now free. What should it be on the base layers?"="GUI / Super key". You can now continue with the user's answers in mind.
All resolved. Let me capture the complete updated base-layer design in the plan file. Here's the full picture I'll record:
Base layers (Colemak default / QWERTY), left→right:
Row1: < RAISE TAB <letters> ... <letters> &kp LGUI
Row2: &ht LSHFT BSPC <letters> ... <letters> < LOWER SQT
Row3: &ht LC(LSHFT) LBKT <letters> ... <letters> &ht RSHFT RBKT
Thumbs: < LOWER ESC &mt LALT SPACE &mt LCTRL DEL | &kp RET &mo RAISE &ht LC(LALT) DOWN
Let me update the keymap blocks in the plan file. First let me see the current state of those blocks.

Actually, changed my mind. Let's make the left thumb cluster's ESC a permanent lower layer key and the right backspace ESC (Hold=Win key)
Let me make sure I capture both changes precisely.
Change 1 — Left thumb, leftmost key: Currently < LOWER ESC (tap Esc / hold LOWER). You want it a permanent LOWER layer key → &mo LOWER (momentary LOWER, no tap action). That frees Esc from this position.
Change 2 — Top-right key: Currently &kp LGUI. You want Esc on tap / hold Win(GUI) → &ht LGUI ESC (tap Esc / hold LGUI).
So Esc moves from the left thumb to the top-right key (as a tap), and that key also gives you GUI on hold. Let me update the keymap blocks.

Now update the prose description in the customizations section.

No left LOWER key should be momentary when held, permanent when tapped. Same logic for it's symmetrical counterpart on the right side but for raise: tap for permanent, hold for momentary
Ah, you want tap = sticky/toggle (permanent) layer, hold = momentary for both thumb layer keys. That's a specific behavior. Let me get the ZMK mechanism right.
ZMK doesn't have a single built-in behavior that does "tap = toggle layer, hold = momentary layer" out of the box. But it's achievable with a hold-tap where:
&mo (momentary)&tog (toggle layer on/off)So I'll define a custom hold-tap behavior (e.g. lt_tog) with bindings = <&mo>, <&tog> and the hold-preferred flavor (so holding reliably gives momentary). Then:
<_tog LOWER LOWER — tap toggles LOWER, hold = momentary LOWER<_tog RAISE RAISE — tap toggles RAISE, hold = momentary RAISELet me confirm one nuance about "permanent when tapped":
User has answered your questions: "For 'permanent when tapped' — should a tap TOGGLE the layer (tap once to turn on, tap again to turn off), or LATCH it on (and you exit some other way)?"="Toggle on/off (Recommended)". You can now continue with the user's answers in mind.
Toggle on/off it is. Let me update the plan: add the custom lt_tog hold-tap behavior and wire both thumb layer keys to it.
First the behavior definition — let me find the behaviors block in the plan.

All updated. Here's the final state of the layer-access thumb keys:
Left thumb (leftmost): <_tog LOWER LOWER
Right thumb (middle): <_tog RAISE RAISE
Powered by a new custom lt_tog hold-tap behavior (bindings = <&mo>, <&tog>, hold-preferred flavor so a deliberate hold reliably gives momentary).
Also still in place from before:
&ht LGUI ESC — tap Esc / hold GUIOne behavior note worth knowing: because lt_tog uses hold-preferred, holding past the 200ms tapping term commits to momentary even if you don't press another key. A very quick tap toggles. If you find quick taps occasionally registering as momentary (or vice versa), we can tune tapping-term-ms.

Done. CI build passed — both halves (corne_left + corne_right with nice_view) compiled successfully.
Ported your QMK Iris keymap to the ZMK Corne v2, committed (e3e487a), pushed to main, and verified the GitHub Actions build is green.
What shipped:
config/corne.keymap — 5 layers:
` 1-0 -), nav, media, =/\! @ # $ % / ^ & * ( )), brackets, volumeconfig/corne.conf — RGB underglow, display, idle sleep, no-RGB-on-bootREADME.md — full usage tutorial with layer diagrams, the dual-function key table, and notes on numbers/symbols/Bluetooth.gitignore — excluded .opencode/ (local plan state)Next step — flashing: Download the .uf2 artifacts from the Actions run, then flash both halves (double-tap reset or press BOOT on the Adjust layer, copy the matching .uf2).
A couple of behavior notes to keep in mind once flashed:
[/Ctrl+Shift pinky mod-taps use a 200ms balanced hold — if they trigger too eagerly during fast typing, we can bump tapping-term-ms.I realized two things:
Good refinements. Let me look at the current LOWER layer arrows and think through both.

Let me address both.
1. Inverted-T arrows on LOWER. Your proposed layout:
... HOME UP END \
PGUP LFT DWN RGT PGDN ...
That gives the classic inverted-T (UP on top-middle, LFT/DWN/RGT below) with HOME/END flanking UP and PGUP/PGDN on the outer edges. This maps cleanly onto the right hand's top + home rows. Note this moves \ — currently \ is the right-pinky on the home row. In your layout \ sits at the end of the top row (right of END). I'll place it there.
2. Ctrl+arrow word-movement. Your two options:
Ctrl+Left/Ctrl+Right keys.Option (b) is elegant but tricky: combining "hold = Ctrl modifier" with "hold = layer shift" on one key needs a custom behavior, and getting Shift into the mix (you mentioned sometimes Shift too) makes it more complex. The cleaner, more flexible ZMK approach for word-movement + selection is mod-morph / dedicated combos, but the simplest robust solution is dedicated Ctrl+arrow keys on a layer.
Let me ask how you want to handle the Ctrl/Shift word-movement so I build the right thing:
User has answered your questions: "How do you want Ctrl+Left/Right (word jump) and Shift variants (selection) accessible? You mentioned Ctrl+arrows and sometimes Shift too."="Actually, we just need to swap the RSE with DWN on the right thumb cluster for symmetry and also make that DWN/C+A simply GUI. This way I should be able to hold down my left thumb on DEL/CTL and right thumb on RSE and activate the arrows. This means the numbers go to the RAISE layer and we get rid of the symbols as I can already get the symbols with raise + shift + numbers", "For the inverted-T, where should HOME/END and PGUP/PGDN go relative to the arrows? (your sketch had HOME/END flanking UP, PGUP/PGDN on the bottom outer)"="As sketched: HOME UP END / PGUP LFT DWN RGT PGDN". You can now continue with the user's answers in mind.
This is a significant redesign. Let me make sure I fully understand before changing anything, because it restructures the layers and thumb cluster.
Let me restate what you're asking:
Right thumb cluster change (both base layers):
ENT · RAISE · DOWN(C+A)ENT · DOWN · RAISE, AND change that DOWN key to just GUI.&kp RET · &kp LGUI · <_tog RAISE RAISE?Wait — let me get the positions exact. The right thumb has 3 keys (inner→middle→outer as laid out left-to-right in the file: RET, middle, outer). Currently: &kp RET <_tog RAISE RAISE &ht LC(LALT) DOWN. You want to swap RAISE with DOWN and make the DOWN-position become GUI.
Layer restructure:
1, then Shift gives !).Here's my concern about the "hold DEL/CTL + RSE to get arrows" idea: holding the left DEL/CTRL key gives you Ctrl held, and holding the right RAISE key activates the RAISE layer. So "Ctrl + RAISE-layer arrows" = Ctrl+arrow. That's clever — it reuses your existing mod-tap. But it means the arrows must be on the RAISE layer itself (not a separate layer), since RAISE is what the right thumb activates.
So the picture becomes: RAISE = numbers (top row) + inverted-T arrows + nav, and holding Ctrl(left thumb) while on RAISE gives Ctrl+arrows naturally. Let me confirm the details:
User has answered your questions: "Let me confirm the layer restructure. RAISE becomes the single 'function' layer holding BOTH the number row AND the inverted-T arrows/nav, and the separate symbols (old RAISE) layer is deleted entirely?"="Yes — RAISE = numbers + arrows/nav, drop symbols", "For the right thumb cluster (inner ENT / middle / outer), what exactly should the 3 keys be after the swap?"="ENT(hold=RCTL) / GUI / RAISE layer (tap-toggle/hold)", "Since GUI is moving onto the right thumb, the top-right key is currently ESC/GUI (tap Esc / hold GUI). Keep it, or change it?"="ESC/C+A". You can now continue with the user's answers in mind.
Now I have the full picture. Let me lay out all the changes:
Right thumb cluster (both base layers), inner→middle→outer:
&ht RCTRL RET — Enter / hold Right Ctrl&kp LGUI — GUI<_tog RAISE RAISE — RAISE (tap-toggle / hold-momentary)Top-right key (both base layers):
&ht LC(LALT) ESC — Esc / hold Ctrl+AltLOWER layer: Deleted entirely (was symbols). Layer count drops to 4.
RAISE layer: Becomes numbers + inverted-T arrows/nav:
` 1 2 3 4 5 | 6 7 8 9 0 -
= . . . . . | HOME UP END \ . .
. . . . . . | PGUP LFT DWN RGT PGDN .
Wait — let me reconcile the inverted-T with the number row sharing one layer. The top row is numbers (` 1 2 3 4 5 / 6 7 8 9 0 -). The inverted-T needs HOME UP END on a row and PGUP LFT DWN RGT PGDN below. If numbers occupy the top row, then nav goes on the home + bottom rows of the right hand.
There's a conflict: your sketch has HOME UP END \ as one row and PGUP LFT DWN RGT PGDN as the next. With numbers on top, nav fits on home row (HOME UP END ) and bottom row (PGUP LFT DWN RGT PGDN). That works. Let me confirm the media keys placement, since old LOWER had media (prev/play/next) that now has nowhere to go.
User has answered your questions: "Merging numbers + arrows onto RAISE: numbers go on the TOP row, nav on home + bottom rows of the right hand. Where should the media keys (prev/play/next) and volume go? The old layers had media on home-row-left and volume on bottom-left."="Media + volume on RAISE left hand", "Confirm: with arrows on RAISE's right-hand home/bottom rows, holding left-thumb DEL/CTRL + right-thumb RAISE gives Ctrl+arrow word movement. And the inverted-T layout is: home row = HOME UP END \, bottom row = PGUP LFT DWN RGT PGDN. Right?"="Yes, exactly that". You can now continue with the user's answers in mind.
All confirmed. Let me set todos and implement. The new structure is 4 layers: Colemak(0), QWERTY(1), RAISE(2), ADJUST(3). Since LOWER is gone, ADJUST can no longer be a LOWER+RAISE conditional — I need to rethink ADJUST access. Let me note that and ask nothing further by picking the sensible option: with only RAISE as an access layer, ADJUST is best reached as a dedicated momentary/toggle. But there's also the left thumb that was LOWER. Let me re-examine the thumb clusters since LOWER is being removed.
<path>/home/byk/Code/zmk-config-corneview/config/corne.keymap</path>
<type>file</type>
<content>
61:
62: keymap {
63: compatible = "zmk,keymap";

65: // -----------------------------------------------------------------------------------------

68: // | [/C+S | Z | X | C | V | B | | K | M | , | . ...
I see the current thumb setup. Now there's a design question I need to resolve: the left thumb inner key is currently LOWER (<_tog LOWER LOWER). With LOWER removed, what happens to that key, and how is ADJUST reached?
You said earlier: hold left-thumb DEL/CTL + right-thumb RSE to get Ctrl+arrows. So the left thumb is: inner=LOWER (now orphaned), middle=SPACE/ALT, outer=DEL/CTL.
Let me think about the cleanest mapping. Since LOWER is gone, options for the left-inner thumb and ADJUST:
The user dismissed this question
Finally, since we moved numbers from LOWER to RAISE, the RAISE layer can be the adjust layer then? We should put F12 to top left tho since we already have boot on the right side
Good thinking — but let me clarify a likely conflict before I build it. You've now got two different roles wanting to live on RAISE:
Those are a lot of keys to put on one layer — numbers occupy the whole top row, arrows occupy the right home+bottom rows, media/volume the left rows. There's no room left for F-keys, BT, and RGB on the same layer.
So "RAISE can be the adjust layer" can mean one of two things. Let me confirm which you intend:
User has answered your questions: "You said RAISE can be the adjust layer now. But RAISE is already full (numbers + arrows + media/volume). How do you want to combine ADJUST functionality (F-keys, BT, RGB, layout switch, bootloader)?"="Sorry I meant the LOWER should be replaced with ADJUST". You can now continue with the user's answers in mind.
That clears it up. So the layer slot that was LOWER becomes ADJUST. Final structure:
Layers:
Left-inner thumb (<_tog LOWER LOWER) → <_tog ADJUST ADJUST (tap-toggle / hold-momentary ADJUST).
ADJUST changes you specified: move F12 to top-left (BOOT is already top-right).
Right thumb cluster → &ht RCTRL RET · &kp LGUI · <_tog RAISE RAISE.
Top-right key → &ht LC(LALT) ESC.
Let me also handle: the '/LOWER mod-tap on the mid-right (< LOWER SQT) — LOWER no longer exists. I'll make it < RAISE SQT? No — that'd add another RAISE access. Better: just plain &kp SQT, or < ADJUST SQT. Let me confirm that one small thing and the conditional-layers removal.
User has answered your questions: "The mid-right key was tap ' / hold LOWER (< LOWER SQT). LOWER no longer exists. What should it become?"="Plain ' (apostrophe)", "The ADJUST layer was previously reached via a LOWER+RAISE conditional layer. Since LOWER is now ADJUST itself, that conditional is removed and ADJUST is reached directly by the left-inner thumb. Confirm removing the conditional_layers block?"="Yes, remove conditional, ADJUST = left-inner thumb". You can now continue with the user's answers in mind.
All confirmed. Let me implement the full rewrite now.

Done — committed (c7f6f22), pushed to main, and CI build is green.
Layers (now 4):
Thumb clusters (base layers):
ADJUST(tap-toggle/hold) · Space/Alt · Del/CtrlEnter/RCtrl · GUI · RAISE(tap-toggle/hold)Other:
' now plainWord movement: hold left Del/Ctrl + right RAISE, then use the inverted-T arrows → Ctrl+Left/Right by word (add physical Shift for selection).
The README was rewritten to match, with updated layer diagrams and a section explaining the Ctrl+arrow word-movement technique.
Next: grab the .uf2 artifacts from the build run and flash both halves.
One thing worth a quick gut-check when you test: the right-inner Enter now holds Right Ctrl, and your word-movement combo uses the left Del/Ctrl. Both give Ctrl, so either works — but if you instinctively reach for the right Ctrl while on RAISE, that also works for Ctrl+arrows. Let me know if the inverted-T positions or any mod-tap feel off once you've typed on it.
actually, let's move the right shift to holding of ' for symmetry, move the C+A to bottom right corner's hold. Remove RSE from top left
Let me make sure I map these three changes precisely against the current keymap.

Let me confirm the three changes against the current state:
"Move right shift to holding of '": mid-right key currently &kp SQT → becomes &ht RSHFT SQT (tap ' / hold Right Shift). And the old bottom-right &ht RSHFT RBKT loses its shift → becomes... see #2.
"Move C+A to bottom-right corner's hold": Ctrl+Alt currently lives on top-right &ht LC(LALT) ESC. Move it to bottom-right corner. Bottom-right is currently &ht RSHFT RBKT (tap ]). So bottom-right becomes &ht LC(LALT) RBKT (tap ] / hold Ctrl+Alt). That also resolves where ] keeps its tap. And top-right ESC loses C+A.
"Remove RSE from top left": top-left < RAISE TAB → becomes plain &kp TAB.
There's one consequence to flag and one ambiguity:
User has answered your questions: "After moving Ctrl+Alt to the bottom-right corner, what should the top-right key (currently Esc / hold Ctrl+Alt) become?"="Plain Esc (no hold)". You can now continue with the user's answers in mind.
All clear. Applying the four resulting changes to both base layers:

CI is green. Committed (1442d90) and pushed.
Base-layer mod-tap tweaks (both Colemak & QWERTY):
TAB — RAISE removed, now plain TabESC — plain Esc (Ctrl+Alt moved away)' — now tap ' / hold Right Shift (symmetric with the left Bspc/Shift)] — now tap ] / hold Ctrl+AltSo Shift is now symmetric (left Bspc + right '), and Ctrl+Shift / Ctrl+Alt sit on the two bottom corners.
RAISE access is now solely the right-outer thumb — your Ctrl+arrow word-movement (left Del/Ctrl + right RAISE) is unaffected.
README diagram and the dual-function key table were updated to match.
Next: grab the .uf2s from the latest build and flash both halves.
