prefix+? — Open the Help / cheatsheet window

Language · 中文 · English · 日本語

← Back to Settings Help

prefix+? opens the Settings window and jumps to the Help page (cheatsheet).

Default chord: ? · Config key: open_help · Set via the [actions] open_help key in the config file (not currently listed in the Settings → Hotkeys editor)

Implementation detail of the default key

Users see ?, but internally the engine treats it as equivalent to the / key:

  • No need to hold Shift.
  • On Chinese / English / Japanese keyboards alike it uses the / key (typically next to .).
  • Assigning ? to another action on the Hotkeys page won’t conflict, because the engine does shift-OEM alias normalization.

Behavior

After prefix+?:

  • If the Settings window is already open → jump to the Help tab and bring the window to the foreground.
  • If the Settings window is not open → open it and land on the Help page.
  • No visual side effects / does not change the current layout / does not change selected_region.

What the Help page shows

The Help page is a dynamically generated cheatsheet:

  • Current prefix (reflects edits to prefix immediately).
  • All bindings: each shown as prefix → <key> with its description.
  • All built-in actions: each shown as prefix → <chord> with the action’s description.
  • Documentation and support links: online docs, report an issue, About gmux.

Edits to bindings / chords automatically refresh this page through the config-reloaded event.

Relationship to F1

When the Settings window is focused, F1 is equivalent to prefix+?.

Exception: F1 doesn’t respond on the About and Open-source licenses pages (to avoid interrupting reading). Use the sidebar to reach Help from there.
