The qualifier should be set in order to support shift-clicking. The method I
use is to open keyboard.device, then issue KBD_READMATRIX like so:

	UBYTE keys[13];

	kbd_ior->io_Command = KBD_READMATRIX;
	kbd_ior->io_Length = 13;		/* SEE NOTE BELOW */
	kbd_ior->io_Data = (APTR) keys;
	DoIO(kbd_ior);

	event.ie_Qualifier |= keys[12];

The bits in the keys[12] are conveniently in the same order as the
qualifier bits.

NOTE: 13 is the only length that works, although if that's documented
      anywhere, it's news to me.

You need to time stamp the events in order for double-clicking to work
correctly. I use timer.device, but I think you could also call Intuition
and get the same thing.

This goes for general mouse events. If you have a specific need just to move
the mouse under program control and you're not doing any clicking, then I
think it's safe to forget about the time stamps and the qualifiers.
