Better Screenshots 

Most tech writers have their favorite software for capturing and processing static screen shots. I won’t compare these applications or try to tell you how to use them. Instead, I’ll give you techniques that help you produce the best possible screen shots, no matter what application you choose. This article assumes that you’ve taken screen shots before. It uses terms like “hot keys” and “time delay” and “capture cursor.” If you don’t know what these terms mean, look them up in the help for your screen capture software. They represent standard features that are found in most screen capture applications.
