Extended keys are the right Ctrl and Alt, Arrow, Insert, Delete, Home, End, Page Up and Page Down keys not on number pad.


  • The extended keys might return the Left Shift release scancodes instead of the press code + 128 when read by INP(96).
  • The Number Lock key could be set so that the Left Shift return code was not returned, but the lock could be either on or off.
  • The 170 left shift release code is not returned by QB64 when INP($H60) is used to read the extended release scancodes.
