  keys_return
	    Returns an array of bytes that identifies which keys are pressed down.  Each bit represents one key of the keyboard.

Description
  XQueryKeymap()  returns a bit vector for the logical state of the keyboard, where each bit set to 1 indicates that the corresponding key is
  currently pressed down.  The vector is represented as 32 bytes.  Byte N (from 0) contains the bits for keys 8N to 8N+7 with the least  sig-
  nificant  bit in the byte representing key 8N.  Note that the logical state may lag the physical state if device event processing is frozen
  due to a grab.
