codex - 💡(How to fix) Fix Add shortcut to jump to top of recalled multi-line composer history

What variant of Codex are you using?

CLI

What feature would you like to see?

Please add a keyboard shortcut in the Codex CLI composer to jump directly to the top of the currently recalled multi-line history entry.

Current behavior, as far as I can tell:

• Up Arrow / Ctrl+P moves up through the recalled message line by line, or through prompt history depending on cursor position.
• Home / Ctrl+A jumps to the start of the current line, not the top of the full multi-line recalled message.
• Ctrl+R reverse-searches prompt history.
• Ctrl+T opens the transcript overlay; inside that overlay, Home and End jump to the top/bottom.

The missing workflow is: recall a long prior multi-line prompt in the composer, then jump to the first line of that recalled prompt with a single shortcut. This would make editing and resubmitting long prompts much easier.

A possible behavior would be one of:

• Add a dedicated composer binding for “jump to start of recalled multi-line input”.
• Make Home / Ctrl+A jump to the start of the full composer buffer when the recalled input spans multiple lines, if that fits the existing keymap model.
• Add PageUp/PageDown-style composer navigation for larger vertical jumps within multi-line input.

Additional information

This came up while trying to edit a long previous prompt recalled with Up Arrow. The transcript overlay has top/bottom navigation, but that does not solve editing the recalled composer text itself.
