How do you dump the screen in Mac OS X when you can’t reach for a hot-key-chord? The answer is grab.

written by Mark Wheadon

Mac OS X Leopard has a tool to dump all or part of the screen built into the desktop, with handy (if difficult to remember) hot key-chords:

  • cmd+shift+3 to dump the whole screen
  • cmd+shift+4 to select an area of the screen (then press space for a whole window).

However, there are times when the above won’t do. Typically, it’s when you’re already pressing keys to get the image you need — the key chord cmd+shift+4 isn’t going to work if you’re already holding down alt for example.

That’s where grab comes in — it’s what Mac users used before cmd+shift+3/4 came along, it’s still there, and it can dump the screen after a ten second delay.

So, start up grab. I use Spotlight to do that, so I type cmd+space grab:

spotlight grab

Then, to do the delayed screen dump, select Timed Screen from grab‘s Capture menu:

grab timed screen dump

You then have ten seconds to set up the screen as needed, and grab does the rest.

Then select File->Save As… to save the resulting tiff file, and you’re done.

    Actually, those key commands for taking screen shots go way back to the original Mac OS in the 1980s.
