Rebinding ESC to \

[Lorenzo Bertini]

Hi LyX users!

I have a keyboard that doesn't have the function keys, so the ESC button 
also contains the \ key. You can probably see where this is going: every 
time i want to type \ I have to press FN and then ESC.

How could I make it so ESC is not "escape" (which I don't really need) 
but instead "input \"? I figured I have to edit keybinds, but what would 
the correct command be?

All the best,

Lorenzo
