Changing the term "keys" in input routine

I wonder if a more console-focused term such as "buttons" could be used instead of "keys" for the following-
- UpdateKeys
- wCurKeys
- wNewKeys

From what I can tell the comments in the code itself uses the word "buttons" and "directions" to refer to the face buttons and d-pad and that "keys" are meant to encompass both of these but I still feel like it's a word not quite suited for the purpose.
