Just looking into elementary OS, and it looks really attractive. I'm a heavy Emacs user; consequently I feel at home on macOS where I can hit
Ctrl-k, etc. to move around, delete lines, etc.
Does elementary OS allow you to set those keystroke system-wide? I'd like to be able to, say, use those when I'm entering text on StackExchange as well as within the address bar of a browser or anywhere I have to enter text.
