((uppercaseCharacter) - ('A' - 1))

Calculate the key code value of Ctrl-{character}, given the uppercase character.

If a key is pressed while holding Ctrl, OSG "helpfully" gives you the key code of the control character (i.e. ^A == 1) instead of the key itself ('A' == 65). To cope with this, you can use CONTROL_CHAR_FROM_UPPERCASE('A') which is easier to read than strange character ('\001') or integral (1) constants.
