Event for Keyboard
KeyPress: if a keyboard button is pressed.
KeyDown: when holding down a keyboard key.
KeyUp: when the user releases a keyboard key.
In addition to the above terms, there are several other terms, the Procedure. In programming we can break the commandments of procedures and programs in a particular function. This facilitates the programming because it is more structured, and there are procedures that can be used repeatedly, makes it easy to program maintenance, it is easier to identify the bug.
