Cursor CLI's Ctrl+Z suspends the process instead of undoing — and there's no alternative

Cursor CLI

Describe the request

Problem

The Cursor CLI prompt input box has no undo/redo functionality. This is a basic expectation for any text input, and it makes editing multi-line prompts frustrating.

What happens today:

  • Ctrl+Z sends SIGTSTP and suspends the process, instead of undoing the last edit.
  • Vim mode (/vim) does not implement u / Ctrl+R either — I checked the current CLI bundle; only navigation and delete commands are present.
  • There is no edit history stack for the prompt input box.

Why this matters

A lot of prompts in the CLI are long and multi-line. It is easy to accidentally delete a paragraph, overwrite text, or make a bad edit. Without undo, the only recovery is to retype the whole prompt or fish it out of shell history, which is slow and unreliable.

Expected behavior

At minimum:

  • Ctrl+Z should undo the last change in the prompt input box.
  • Ctrl+Shift+Z (or Ctrl+Y) should redo.
  • If that is not possible because Ctrl+Z is reserved for process suspension, then provide an alternative shortcut and document it.

Related requests

  • An official Cursor CLI keyboard shortcuts reference page. Right now shortcuts are scattered across Using Agent in CLI and Terminal setup. A single page listing all prompt input shortcuts, plus what’s missing, would help a lot.

I posted this in the older feedback thread too, but I think the issue is important enough to deserve its own focused thread. Happy to help test any implementation.
