CTRL+X+E in ZSH

Question

In BASH a CTRL+X+E opens $EDITOR and, on exit, BASH executes that command. When i run CTRL+X+E in BASH, i do need to SAVE it before exit.

What is the equivalent in ZSH to BASH's CTRL+X+E?

What is ZSH's Alt+X?

What is ZSH's Alt+X?

we can figure that out using bindkey:

"\M-^@"-"\M-^?" self-insert

We find "^[x" execute-named-cmd. Aha! That doesn't tell us anything!

So, we go and read man zshzle (the man page for the zsh line editor), and find that execute-named-cmd can be used to execute any of the other commands outlined in that document. For example,

Alt+xdescribe-key-briefly enter

(you can use tab completion here!)

puts us into a mode where we can type in key combinations and get what commands they bind to. (for example, try pressing Alt+x here!)

What is the equivalent in ZSH to BASH's CTRL+X+E?

maybe edit-command-line? try Ctrl+x Ctrl+e, that's what it's bound to in my shell, or try running it manually, via Alt+xedit-command-line enter.
