Search a game by letter or name

[gepponline]

Hi!
   I'm new with Attract- mode but i love it!
I've tried retropie before, but i prefer attract.
I'd like to use it to make an aracde cabinet using an old pc with ubuntu.
It's working good at the moment but I'd like an easy way to filter games by letter using the joystick.
Is there a way to do it?
Even a complete search but using only joystick could be very very nice

You can set next and previous letter controls I believe.

Or create a filter for each letter of the alphabet.
