Event.KeyboardEvent

static function KeyboardEvent (key : String) : Event

Description

Create a keyboard event.

This is useful when you need to check if a certain key has been pressed - possibly with modifiers. The syntax for the key string is a key name (same as in the Input Manager), optionally prefixed by any number of modifiers:
& = Alternate, ^ = Control, % = Command/Windows key, # = Shift
Examples: &f12 = Alternate + F12, "^[0]" = Control + keypad0 .
