Add Ctrl+H as backspace keyboard shortcut #2391
Description
What feature would you like to see?
Currently, Codex CLI supports Ctrl+D for forward delete, but doesn't support Ctrl+H for backspace. Many terminal applications following readline conventions support both:
- Ctrl+D: Delete character under cursor (forward delete)
- Ctrl+H: Delete character before cursor (backspace)
This would improve consistency with standard terminal keybindings and make text editing more efficient for users familiar with readline-style shortcuts.
Current behavior:
- Ctrl+D works for forward delete ✅
- Ctrl+H doesn't work for backspace ❌
- Users must use the Backspace key only
Expected behavior:
- Both Ctrl+D and Ctrl+H should work
- Ctrl+H should delete the character before the cursor, same as Backspace key
Version: codex-cli 0.22.0
