^X^E in bash takes your current prompt and moves it to your $EDITOR.

for zsh:

  autoload edit-command-line
  zle -N edit-command-line
  bindkey '^X^E' edit-command-line

Other shortcuts to edit prompt in editor:

Alt-e for fish

Ctrl-g for Claude code

Right, but if all terminals behaved like modern pieces of software, we would take functionality like Warp's as given, instead of suggesting workarounds.

What you describe sorta works, but you lose things like file/dir-based autocomplete, since your editor doesn't know about your shell session.
