How to bind to Escape key?

I noticed that escape key doesn't do anything useful in some states of the UI so I'm looking for a way to bind it to actions. E.g. it would be handy if I could bind Esc to switch between Orders / Units when factory command panel is active.

Same with whitespace, when you press the space bar nothing happens in the binding dialogue.

Does anyone know how to do it?

mouse 4/5 didn't work for me

but I've found the way https://zero-k.info/mediawiki/index.php?title=Keybind_file
