Before submitting

• I searched existing issues and did not find a duplicate.
• I included enough detail to reproduce or investigate the problem.

Area

apps/web

Steps to reproduce

1. On macOS, set the following keybinding in the keybindings config:

[
  {
    "key": "ctrl+shift+option+cmd+s",
    "command": "terminal.toggle"
  }
]

2. Open the desktop app to a normal chat view.
3. Ensure the command palette is closed and the terminal is not focused.
4. Press Ctrl+Shift+Option+Cmd+S.

Expected behavior

terminal.toggle should fire and the terminal drawer should open or close.

Actual behavior

The keybinding is accepted by config parsing/loading, but pressing the shortcut does not trigger terminal.toggle.

Impact

Major degradation or frequent failure

Version or commit

Desktop app 0.0.20; locally verified against main @ 40b3a800

Environment

macOS, desktop app 0.0.20

Logs or stack traces

No keybinding parse error after updating to this shortcut.

Locally, the issue traced to `apps/web/src/keybindings.ts` runtime matching relying mostly on `KeyboardEvent.key`, with only limited `event.code` aliases.

On macOS, `Option`-modified letter shortcuts can surface a symbol or dead-key value in `event.key` instead of the physical letter key, so a configured `...+s` shortcut can fail to match at runtime.

Workaround

Use a shortcut that avoids option/alt with letter keys, or use a patched build that falls back to the physical key code for option-modified letter shortcuts.
