Rpg maker key configuration? - rpg maker keys

Already in Google, but all the results for "RPG Maker key gene, which obviously is not what I want.
So, I'm game, and I want to be able to do other things that can activate by pressing ENTER. Has anyone any idea how to use the buttons on a game? As an "A" and so on? Or, if it is a complex tests, we know a script that has brought a kind of person into the game at all?
