Can't get lower case "q" to quit (Documentation Bugs and Problems)
OK, here is the answer to that one.
BASIC256 uses the QT keyPress event to save the "keycode" of the last key that was pressed. This key code is a raw key number and not the ASCII/UNICODE value the key will produce on input. This allows BASIC256 to capture the shift. control, and other keys. See http://doc.qt.digia.com/qt/qt.html#Key-enum for a listing of the keys and codes.
