Quick guide on how to do screen captures (full, partial, active window et.c) on the PC and Mac.
This additional document covers the gaps in capturing just the active window on the Mac.
On the latest versions of OSX you can use grab to do all the leg work.

If you want a handy tool for doing screenshots on Windows (most useful when putting that documentation together), check out Gadwin PrintScreen (http://www.gadwin.com/printscreen). It takes over the PrintScreen key and can be configured to take a shot of the whole screen, active window or rectangular area. It can save in .jpg, allows you to preview the capture and has a nifty zoom area when doing rectangular areas so you can get pixel-perfect captures.
