Fixes #15954. On macOS French AZERTY, Cmd+Option+Shift+A can produce key: "Æ", code: "KeyQ". The shortcut matcher assumes the physical US letter Q when Option hides the layout's letter, so the advertised appearance shortcut does not run (or a Q binding wins).
Use the browser's keyboard layout map for macOS Option-modified symbols. Keep ordinary Latin event.key precedence, explicit symbol matching, and existing physical fallback when the map is absent or non-Latin. Refresh on layout changes without blocking startup, and discard stale async results. Settings shortcut recording uses the same mapping.
This applies to the web client and Electron's shared web UI, including command dispatch and Settings recording. No server, wire contract, provider adapter, mobile navigation, or persisted shortcut migration changes. The map is read on the client, so local and remote environments use the keyboard where the user is typing. Browsers without the Keyboard Map API retain the existing behavior; this does not claim to fix their unavailable layout information. API reference: https://wicg.github.io/keyboard-map/.
Issue #15954 is labeled bug and via-triage. This continues the existing focused fix for that reported shortcut failure.
November 7 integration: current head b076ad39a7 includes main at e455200077ce. vp run check:changed passes 68 tests, 34 affected-package typechecks and React Compiler checks.
Actual Chromium startup and Settings recording before/after: the browser no longer crashes when its Keyboard object lacks EventTarget methods. A focus refresh preserves the valid map while the new lookup is pending; layoutchange and current-request failure still clear it. These async transitions have failing-before/passing-after automated coverage.
The evidence below records the earlier implementation and remains revision-specific.
Before implementation, a focused regression with A and Q bindings failed: the captured event incorrectly resolved to sidebar.toggle (Q) instead of appearance.cycle (A).
vp test run apps/web/src/keybindings.test.ts apps/web/src/keyboardLayout.test.ts apps/web/src/components/settings/KeybindingsSettings.logic.test.ts: 53 tests pass, covering the collision, Latin-key precedence, non-Latin/absent-map fallback, AltGraph exclusion, recording, layout changes, rejected lookups, stale completion, and disposal.
vp run check:changed: formatting, lint, knip, affected-package typechecks, and nearby tests pass.
Integrated check in an isolated local macOS web client using Codex's in-app browser. A temporary, uncommitted fixture supplied KeyQ -> a and replayed the issue's captured keydown through a visible button. Before: two replays left appearance at System. After: the first replay changed it to Light; the next changed it to Dark. The fixture and server were removed after verification. No OS keyboard settings or live T3 data were changed.
This is captured-event replay, not native physical French keyboard or packaged Electron validation. No provider turn was submitted.

Preserve physical punctuation shortcuts when the map supplies a letter.
On a layout where Semicolon maps to m, an Option event with key: "µ" now produces µ and m as candidates. It no longer produces ;. An existing Option+; binding therefore stops matching that physical key, although punctuation shortcuts otherwise use physical positions. Keep the punctuation-code candidate when adding a mapped letter; retain the current suppression of physical letter candidates. The Keyboard Map specification confirms that its values describe keys without modifiers. (wicg.github.io)

✅ Addressed in commit fa95517
Confirmed and fixed in fa95517b3a. A regression first reproduced the missing Option+semicolon binding for key µ / code Semicolon mapped to m. Candidate generation now preserves the original punctuation candidate alongside the mapped letter, without reintroducing physical letter collisions. Both isolated bindings pass; existing A/Q precedence and Latin event-key tests remain green. All 54 focused tests and check:changed passed.
@nateEc Thanks for the fix. The supplied code preserves ; alongside µ and mapped m, without restoring the physical letter fallback. This addresses the finding. Your reported regression tests cover both bindings and the existing letter precedence.

| 5 | Learning: In `apps/web/src/keybindings.ts`, shortcut matching and recording use `KeyboardEvent.code` to preserve physical-key behavior across keyboard layouts. Do not statically normalize shifted symbol aliases in `shortcutConflictKey()`, because symbols such as `"` and `'` can originate from different physical keys on layouts such as UK keyboards. |

Merged main c3888da8b4 in 15c03c2eed. The startup conflict is resolved by preserving keyboard-layout tracking/HMR cleanup and using main's startAppServices entry point (without restoring obsolete router/auth initialization). check:changed passes all scoped gates, 55 tests in three files, and affected-package typechecks. Existing keyboard behavior/evidence is unchanged.
Heads-up: this also fixes a SnapShot bug on macOS, which is worth keeping in mind when you test it.
The SnapShot shortcut recorder calls keybindingFromKeyboardEvent, so on main Option+letter stores the symbol instead of the letter. ⌃⌥⌘J records ∆, and Settings then shows "The system could not register this shortcut." I saw that in the real desktop app while testing #22934.
I checked this PR at 15c03c2eed with a throwaway test: with the layout map loaded, { key: "∆", code: "KeyJ" } with Cmd, Ctrl and Option held records mod+ctrl+alt+j. I haven't tried it in a real desktop build, so the SnapShot flow itself is untested here.
Claude Opus 5.5 (Claude Code desktop app)
Tested this on macOS with a native Dvorak layout (com.apple.keylayout.Dvorak). It fixes a second layout, plus one startup crash to fix first.
Startup crash in Chrome. At 15c03c2, the web client fails to load with keyboard?.addEventListener is not a function. Chromium's navigator.keyboard has getLayoutMap() but isn't an EventTarget, so the ?. in trackKeyboardLayout doesn't guard it. The tests use a fake keyboard that has addEventListener, so they don't catch this. I haven't run the unmodified PR build in Electron, but it uses the same Chromium. Locally, keyboard?.addEventListener?.(...) / removeEventListener?.(...) fixes it. Chromium never fires layoutchange, so refreshing the map on window focus is probably also needed.
Dvorak results with that guard applied (vp run dev:desktop):
{"key":"Dead","code":"KeyL"}. On main this resolves as l, so chat.newWithoutProject (mod+alt+n) never fires.getLayoutMap() returns KeyL → n.KeyN) opened a projectless thread on main; with this PR it toggles the right panel ✅Side note: Chrome takes ⌥⌘N for split view on macOS, so the web build can't test or use this shortcut in Chrome.
Fixed the Chromium startup blocker and the missing focus refresh in d985edb31f, after merging main e455200077ce without rewriting existing commits.
Before: Chromium startup failure
After: Running client and recorded shortcut
Model: GPT-6. Harness: Codex desktop.

Keep the map during a focus refresh.
While the lookup is pending, an Option shortcut can miss its layout letter or match a physical-key binding instead. Keep the previous map for focus refreshes, but clear it on layoutchange and on a failed current lookup. If the layout changed while the window was unfocused, the old map can still be used until the focus lookup completes.

✅ Addressed in commit b076ad3
Confirmed and fixed in b076ad39a7. A focus refresh now keeps the last valid layout until the current lookup settles; a known layoutchange still invalidates immediately, and a failed current request clears the map. Revision guards continue to ignore stale results. The existing recording regression now holds the focus lookup pending and verifies Option shortcuts before and after completion, including rejection and disposal for both browser keyboard API shapes. It failed on the previous implementation. vp run check:changed passes: 68 tests, affected-package typechecks, formatting/lint/Knip and React Compiler checks.

@nateEc Thanks for the fix. I verified that the implementation retains the map during focus refresh and clears it on layoutchange or a current lookup failure.
Two requested regression checks remain:
layoutchange invalidation when a valid map is already present.Please add these checks and rerun the tests. I did not run the tests here.

Merged main d2c25950b4 in ac78f522a5 (merge commit, no rebase) to clear the conflict in packages/shared/src/keybindingMatching.ts. shortcutKeyFromEvent keeps this PR's layout-map lookup for Option letters and main's unshifted zoom + rule, in that order. The web wrapper now takes shiftKey and altKey to match main's signature. vp run check:changed and the keybinding, keyboard layout, and settings recorder tests pass.
