How to leave the execute prompt in zsh

promptzsh

In a zsh, maybe I pressed Alt+X by mistake,
but now I'm stuck and this execute: _ prompt won't leave.

Pressing Ctrl+C does nothing. 
If I press Enter it tries to complete what I typed.

Pressing Enter on an empty line:

execute: _
zsh: do you wish to see all 373 possibilities (64 lines)?

Typing q and pressing Enter:

execute: quote_
quoted-insert  quote-line     quote-region

In other shells, Alt+X brings the same behavior,
except that Ctrl+C cancels the prompt.

Is there a way to get out or is this shell dead?

Ctrl+G aborts the current editing command in Bash and Zsh if you are in Emacs mode (which is usually the default mode).
