Feature Request: save state slot keys binding

Right now to change save state slots you have to press a key to increase or 
decrease a save slot. This is really cumbersome because not only do you have to 
press a key several times to reach your save slot, but there's also no 
on-screen message telling you the save slot you are on.

I request an option to be able to bind a key to a specific save slot. Most of 
the other emulators have the save slots bound to the 0-9 numbers (you can 
modify them though), but I understand this could be a problem for arcade games. 
But I still believe the option to have independently configurable save slots 
would be great.
