Speaking of touch-enabled devices....

If you don't have a touch-enabled monitor, but you do have a Wacom tablet with
its own pen and wireless mouse, then using the pen on that Wacom tablet is pretty-much the same thing as having a touch-sensitive monitor, except you're doing your thing on the tablet surface, not on the monitor screen.

But the same sorts of actions apply. You tap to click, tap-and-hold for a right-click menu, and you can select or drag very much the same as if you were doing it with a finger on the screen. In fact, the guys who invented the touch monitor were probably using a Wacom tablet when they got their bright ideas.
That's my theory anyway, and I'm sticking to it......
