Hello, in MUGEN cfg file you can edit the keys used in the game. It shows something like this

;[P1 Keys]
;Jump   = 273
;Crouch = 274
;Left   = 276
;Right  = 275
;A      = 44; L
;B      = 46
;C      = 47
;X      = 108; L
;Y      = 59
;Z      = 39
;Start  = 13

Now, I know I can edit these keys within the game, but my question is: Do you know which keys relate to each of those numbers? How can I know? For example, is 1 = a ?
Help please.
