Description
What variant of Codex are you using?
CLI (interactive TUI)
What feature would you like to see?
I'd like a Helix-style editing mode for the prompt composer, alongside the existing Vim mode.
This can't be covered by a Vim keybinding preset because Helix uses selection-first editing: you select text first, then apply actions such as delete, change, or yank.
I don't think full Helix parity is necessary initially. Supporting the core navigation, selection, insert, delete, change, yank, and paste behavior would already be very useful.
Additional information
#9184 added inline Vim editing and is now completed. I searched for an existing Helix-mode request but couldn't find one.

Research direction
Start with the CLI/TUI prompt composer and the inline Vim editing implementation from #9184. Compare its editing model with Helix's selection-first behavior, then define the initial navigation, selection, insert, delete, change, yank, and paste scope. Done means the composer offers a usable Helix-style mode alongside Vim mode.
