Lion Grab of Full Screen

Can anyone please tell me how to use Lion's Grab app to capture a region of a full screen Safari window?

Thanks

Mike

Shift-Command-4 is the magic key combo (you don't need Grab open for this). Click and drag a square.

Thanks for the info on the standard keyboard shortcuts. However, I am trying to learn how Grab works and how I can use it to accompliish the same things. Unfortunately, I just can't seem to get the steps correct.

If say you have Safari in a full screen, you want to use Grab there? That so far I can't figure out, and what Van suggested works so easily, I would just use that method. If it's in a window it's easy. You hit (in Grab) Capture/Selection, then select the area.

So far I do not see a way to do that in a Full Screen window of an application with Grab.

Thanks for checking it out. Sorta limits the usefulness of grab. I thought that grab might be intended to replace the keystrokes eventually. I have a SnagIt license and may install it. It is my main screen capture on Windows.

Regards,

Mike
