I'm trying to map the Return (Enter) key for the Select action and it lets me map it, but if I try to use the enter key to select anything on a popup menu it does not work. I'm trying to use Escape for the Exit action (does work). This will make it so it's just arrow keys and enter/escape for keyboard navigating. This seems much more natural to me.
Thnaks for pointing this out, elkay!
The code has been adapted to allow the 'enter' key use.
