I'll copy it here now that I'm on the computer. When I'm using recalbox I can't access the wiki from android but I can access the forum. I just need a way to take a look at the controls from the phone, although it would be simpler if I could look them from recalbox.
Special In-Game Commands:
In Recalbox, the shortcuts are, for the most part, a combination of keys involving a key named HOTKEY (HK) which must first be defined in the controller's settings options.
The names used for the buttons are those of the Super Nintendo controller (the L1, R1, L2, R2, L3 and R3 buttons are based on the PlayStation controller).
See this page for details.
