Q:

How to Screen Capture while in Cmd+Tab

I ran into a rare situation - I want to snag a picture of my screen while using cmd+tab to show people how I navigate around in this how-to post.  
The regular cmd+shift+3 or 4 didn't do anything.  Thoughts on getting around it?  
I run lion 10.8.3 on a MBA. 

A:

screencapture -T 5 /tmp/screencapture.png # 5 second delay
screencapture -T 5 -cC # -c copies to clipboard, -C includes a cursor
screencapture -T 5 -ic # -i (interactive mode) is like shift-command-4

I also use a function like this:
screencaps() {
  while :; do
    screencapture -C ~/Desktop/$(date +%y%m%d%H%M%S).png
    sleep ${1-1}
  done
}

A:

Open Grab, go to Capture -> Timed Screen, then make sure the cmd+tab module is up on the screen when the timer runs out.  Then open in Preview and crop as desired.
