How do you make button press events?

My question is, how would one make an event call trigger when the player presses a key, say, "H"?

An example: Player press "H" to call an event, $scene = Scene_Open_Menu.new

isn't there an event option for button input?

Conditional Branch: Button Pressed

Also, Button Input Processing: Conditional Branch: Variable


They can each be used for different situations. Regardless, you will probably want a parallel process common event to do it.

that's only useful if you want to use the predefined buttons.  I have no idea if H is one.

There's a script somewhere around for button input.  Have a bit of a search in the scripts database - I'm almost certain I got it from here.
