I have Libre running on a Pi. Connected to a TV with CEC. The TV remote can do everything except whatever would be the keyboard equivalent of "Escape" or "backspace" so I get stuck in menus and need to use the keyboard.
The remote has at least 100 extra buttons I could map... I'm just having trouble identifying the right way to do it.
I have tried the "keymap editor" addon but it doesn't seem to accept my keys. 
"Escape" or "Back" key map for CEC TV/Remote?

Not sure which keys you did, but try this one in keymap.xml. BTW, ESC and Back can have different effects.
Code<FullScreenVideo> <remote> <back>PlayerControl(Back)</back> </remote> </FullScreenVideo>
