Snipping Tool on Vista

In a comment on my post about problems running Cropper on Vista, Chris Hammond pointed out the Snipping Tool that's built into Vista (Programs, Accessories. I wasn't aware of this tool - it's really quite cool! It allows you to draw a rectangle or free form shape on the screen, and captures whatever is displayed on the screen in that region (it also supports the standard window and fullscreen snapshot). Thanks for the pointer, Chris!

 I have a feeling Vista is full of little stuff like this that I'll be discovering in the common months (if not years). Hell, there's still little things I'm discovering in XP! Is there some catalog of new little tasties like this described some where? The "What's New" documentation never seems to cover small stuff like this.
