(Apple added the "Grab" application to the OS because people couldn't Google "screen capture Apple" I guess. I haven't used it.
Last time I tried it, launching either Windows Help and searching for "screen capture" or typing "screen capture" into the Spotlight search bar on OSX both brought up instructions, too.
Spotlight on iOS however has no such help. To capture the screen on an iOS device (iPod Touch, iPhone, iPad) depress the main Home button and the soft power-off button simultaneously. The screen will flash and you'll hear a "camera shutter" sound. Exit the App you were in and open the Photo App, and you'll find that your latest "photo" in the phone's photos is the screenshot.
I think Garmin had even added screenshots to the G1000 recently with a software update, where they write it to a properly sized-prepared memory card in one of the slots, but even Google can't find that one. Kent may know...
Windows screenshots of bugs are so easy I do them in my sleep now. From memory...
PrintScreen (or ALT-PrintScreen usually since PrintScreen grabs the entire virtual "desktop" across all monitors which is annoying), Window Key-R, type "mspaint", ALT-N for new file, click mouse inside drawing area, ALT-V to Paste, File->Save As... Pick a file type and name.
E-mail it off to higher-paid Engineer who should have known better.
