Keyboard Shortcut for saving while in expression editor

A way to save my expression without having to click save would be pretty nice. Something along the lines of shift+enter, ctrl+s while in an expression editor(i know this is used for saving new versions so maybe not this), etc. Most programs have this kind of quick exit for a dialogue box and we already have esc as the way to exit without saving.


Since it’s so easy to escape the expression assistant with the slightest touch of the Esc key - there should be an equally fast save method as well.
