I had been jotting down the key command shortcuts for various permutations of screenshots in OS X to use as a tip when Boris the patient submitted a comprehensive list of 'em:

> Command-Shift-3 [window to disk] OS 9, 10.1.x and 10.2
> Command-Shift-3 + then Control [window to clipboard] OS 9 and 10.2
> Command-Shift-4 [part of the display to disk] OS 9, 10.1.x and 10.2
> Command-Shift-4 + Control [part of the display to clipboard] OS 9 and 10.2
> Command-Shift-4 + Capslock [active window to disk] OS 9
> Command-Shift-4 + Capslock + then control [active window to clipboard] OS 9
> Command-Shift-4 + Spacebar [active window to disk] OS X 10.2
> Command-Shift-4 + Spacebar + Control [active window to clipboard] OS X 10.2

So Boris gets a book and I get to stop stashing those commands away for future use.

But wait, there's more. I happened to visit Ken Bereskin's WebLog again the other day to find he'd also covered Screen Capture. Rather than link to it, here's his bit (it's short and I'm pretty sure he won't mind):

> Screen Capture has also been improved big time in Jaguar. When you use the
> interactive version (command-shift-4), the space bar will toggle between the
> regular marquee selection mode and a new mode to capture just a single window,
> the Dock or the menu bar. The cursor changes to a camera icon when you are in
> this new mode and as you mouse over different areas of the screen the screen
> capture target is highlighted for you.
>
> And of course, there's more... Screen captures can be triggered from the
> command line (and therefore AppleScript, perl, etc.) using the new
> screencapture command found in /usr/sbin/
>
> usage: screencapture [-icmwsWx] [file] [cursor]
>
> -i
> capture screen interactively, by selection or window
>
> control key
> causes screen shot to go to clipboard
>
> space key
> toggle between mouse selection and window selection modes
>
> escape key
> cancels interactive screen shot
>
> -c
> force screen capture to go to the clipboard
>
> -m
> only capture the main monitor, undefined if -i is set
>
> -w
> only allow window selection mode
>
> -s
> only allow mouse selection mode
>
> -W
> start interaction in window selection mode
>
> -x
> do not play sounds
>
> file
> where to save the screen capture

So there you have it. Mac OS screen shooting has never been easier, better, or more flexible. (But Snapz Pro still rocks!!)
