Well, part of it. The items in the action column are done by
intuition, and the commodities code gets input events before they get
to intuition. CX will let you tweak the input events, delete them, and
even insert new ones. So you could probably do:

	Left Mid  Right     Action
	[x]  [ ]  [ ]       LEFT (Select)
	[ ]  [ ]  [x]       RIGHT (Menu)
	[ ]  [ ]  [ ]	    DOUBLE-LEFT (Popup Menu)
	[ ]  [x]  [ ]       DOUBLE-RIGHT (Activate)
	[ ]  [ ]  [ ]       SHIFT-LEFT (Extend Selection)

The Action column indicates what comes out - a left or right mouse
click, two left or right mouse clicks, or a shifted left mouse click
(anyone want to add others). The comment in parenthesis indicate what
the standard action for those buttons is. Others could, of course, be
added.

You can catch double-clicks coming in, but you can't modify the first
click on the way out.

Double-clicks are a pain to design into an interface. They need to
work _after_ a single-click, they need to be an obvious extension of
the single-click action, doubleing the single-click action must be
"safe", and you have to verify that the double-click isn't really a
pair of single clicks that happen to happen that fast. A real mouse
button avoids all those problems.
