Add Readline-compatible keybinding configuration

[ncaq]

I would like to request custom keybinding support for the Claude Code CLI interface.

Proposal

Implement Readline-compatible configuration and automatically load the user's ~/.inputrc file.

Rationale

• I with non-standard keyboard layouts (like Dvorak) currently face usability challenges
• Leveraging existing Readline configurations means users don't need to learn new configuration methods

Example

Here's an example of my ~/.inputrc configuration:

set editing-mode emacs

# control

"\C-b": backward-delete-char
"\C-h": backward-char
"\C-n": history-search-forward
"\C-s": forward-char
"\C-t": history-search-backward

# alt

"\eb": backward-kill-word
"\eh": backward-word
"\es": forward-word
"\et": history-search-backward

Being able to use this configuration with Claude Code would significantly improve my workflow efficiency.

Ctrl-a currently works to go to beginning of line on mac-os, but ctrl-e does not go to the end of the line.

A .inputrc or /emacs option would work for me.

I appreciate ctrl-p and ctrl-n implemented with https://github.com/anthropics/claude-code/issues/33!

Just adding a +1, would really like to edit my text input with vi keybindings, readline would be perfect.

I’d love it if Claude Code let me open the current prompt input in my $EDITOR (the way Bash does with Ctrl-X Ctrl-E, the edit-and-execute-command).

Can this issue be merged with #4950? (Or vice versa?)

This would still be useful, and I don't want to lose priority or the +1s

I'd also really like this. Many text editors allow ctrl+u to delete newlines after deleting to the start of the line, i.e., you can press ctrl+u once to delete a whole line and then press again to go up to the end of the line above. IIUC, I need this feature request to impl this in Claude Code.
