While this can be done in zsh/bash, it takes investment to understand how to use multiline specifically. And then once you leave the terminal, the same keystroke does not do anything for you.

One of Warp is that you don't have to think twice about it because it behaves similarly to text fields everywhere else on your computer.

In the terminal, I often have the feeling that personal computing revolution from Xerox PARC & Apple Computer never happened.

This works in everything that uses libreadline to accept user input (unless the binary has specifically configured library differently iiuc), so should work in all shell-like interfaces. You can customize the shortcuts in inputrc, likewise, for all libreadline-using binaries. By default, readline tries to be emacs-like. You can ask it to be vi-like, or reconfigure lots of its shortcuts to be similar to an editor you like. To be fair, "escape to real editor" is not a thing you usually do in an editor, so that will remain special.
