Screen Capture

My favorite screen capture tool is still SnagIt, which is now in it's 8th version.

I illustrate here how you can blow up a section of the capture for emphasis (you can also darken and/or blur the rest of the image), and you can put an edge on the capture to emphasize that it is a section of a bigger image. You can also add thought balloons, do video captures, and much, much more.
