paste graphic on mousedown

[Kurt Kaufman]

I need to be able to paste small graphic objects with one click.  In 
other words, keep a graphic on the clipboard and paste numerous times 
at locations determined by the point of the arrow cursor. -Sort of like 
an ink "stamp". There would be a few different graphics to choose from, 
and they could be selected by keyboard shortcut, or by clicking on a 
palette. The "stamped" graphics must be moveable.
Does anyone have a suggestion as to the most efficient way of doing 
this?

Thank you,
Kurt
