It is a function that converts keycodes like those used in _KeyDown events, to strings like "Ctrl", "Alt", "F", "/", which are recognizable to the end-user. Great for game programmers.
Inputs
KeyCode as Integer
Assumes
If the user presses Shift+3, the function will not return "#", but will return "3" instead. It also uses easily recognizable symbols to represent certain keys, e.g "~" instead of "`", "\" instead of "|", and "Pg Dn", "Enter", "Space", to represent other keys.
Code Returns
KeyStr as String
Side Effects
If a key inputted does not match with any of the strings listed, the string returned will be "!".
