AOZ Studio V1 (TBD bugs clean/-> V2)

Update: It is only the LEFT modifier keys that get shifted 1 bit. The RIGHT side modifers are OK.

Update 2: Certain combinations also cause a right bit shift.

Examples:
Right Ctrl & Left Meta (shifts the Right Ctrl right one bit - left meta is unaltered)
Right Ctrl & Left Shift (shifts the Right Ctrl right one bit - left shift is unaltered)

Some shifts also happen on key UP event.

Examples:
After holding Right Ctrl & Left Meta, if Cntrl only is released, Left Meta is shifted left one bit.
After holding Right Ctrl & Left Alt, if Alt only is released, Right Ctrl is shifted right one bit.

Also, though Alt is not returned by itself, it is returned when another key is pressed.

Example:
Holding the down arrow, with Right Alt returns Right Alt.
Holding the down arrow, with Left Alt also returns Right Alt.

Other shifts occur:
Holding the down arrow, with Left Meta, shifts Left Meta left 1 bit.
