Codex Desktop: add an assignable keyboard shortcut for Goal mode

What variant of Codex are you using?

App (Codex Desktop on macOS)

What feature would you like to see?

Please add a first-class, assignable keyboard-shortcut command for activating Goal mode in Codex Desktop.

The app currently exposes Toggle Fast mode in Settings > Keyboard Shortcuts, so users can assign a shortcut such as Command+Option+F. Goal mode is available through /goal, but there is no corresponding Goal action in the Keyboard Shortcuts settings.

Suggested behavior:

1. Add an action such as Activate Goal mode or Open Goal mode to Keyboard Shortcuts.
2. Pressing the shortcut should put the current composer into the same state as invoking /goal, ready for the user to enter or confirm an objective.
3. The shortcut should be fully configurable; Command+Option+G would be a natural default if it has no platform conflict.
4. If a goal is already active, the action could open the current goal controls or summary instead of silently replacing it.

This would provide a consistent workflow:

• Command+Option+F: toggle Fast mode
• Command+Option+G: activate/open Goal mode

Why is this useful?

Goal mode is intended for long-running work and is often selected deliberately at the start of a task. A dedicated shortcut would be faster and more discoverable than typing /goal, while preserving the normal confirmation and objective-entry flow.

Related issues and pull requests

• #27840 requests /keymap parity for the Desktop app, but does not add a Goal-specific command.
• #30700 requests binding arbitrary prompt text to shortcuts, which is broader than this request.
• #18077 added the Goal TUI UX and /goal operations, but not a configurable Desktop shortcut.

This request is specifically for exposing Goal mode as a built-in command in the existing Codex Desktop Keyboard Shortcuts settings.
