You can assign a custom shortcut to it via Settings > Keymap and then the action "Main Menu > File > Local History". I myself have assigned the shortcut control+shift+=

Thanks, did that. I decided on Alt+Z, because Ctrl+Z is Undo, so I though this makes sense.

And Ctrl+Alt+Z is revert changes. Either the whole (or selected) file, or the current block you're in. I use it all the time.
