Amazing!

Thanks to follower Paradise Purls,
 LOOK!  A screen shot:

Here is the tip she left in the comments:
 "Ok, I have a mac, too, and this is how I get my screen shots. First, hit command, shift, F for a full screen. Then position the treasury pic on the screen so you see the whole thing. Then, hit command, shift, 4 which brings up the crosshairs. Click and drag to highlight the treasury. Let go and voila, screen shot perfection!"
Works like a charm.   I am so excited.  Even the guys at the Apple store couldn't tell me how to do this.
