Ctrl-F is hard-bound to Find/Search in Codex Desktop, blocking Emacs-style navigation

Title: Ctrl-F is hard-bound to Find/Search, preventing Emacs-style text navigation in Codex Desktop

In Codex Desktop on macOS, Ctrl-F is reserved for Find/Search. In text editing contexts, this prevents the common Emacs-style meaning of Ctrl-F (forward-char).

Expected behavior:

• Text input areas should support configurable keybindings, or provide a built-in Emacs-style keymap.
• At minimum, Ctrl-F should be rebindable in composer/thread text fields.

Actual behavior:

• Ctrl-F triggers Find/Search instead of moving the cursor forward by one character.
• No obvious keybinding customization path is available.

Impact:

• This reduces editing efficiency for users who rely on standard Emacs-style cursor movement in text inputs.
• The issue likely extends to related navigation bindings such as Ctrl-B, Ctrl-A, and Ctrl-E.

Request:
Please add customizable keyboard shortcuts, or an Emacs keybinding mode for text editing in Codex Desktop.
