Coffee Break, Treasury screen shot practice

Ok, Main Etsy Treasuries are a little easier to snag these days with the opening of Treasury East where the treasuries can stay up indefinitely.  I seem to be stumbling on the Main "T's"easily recently.
I love exploring Etsy this way.  Type in a key word, say "coffee," or an Etsy team name, say "Etsy Knitters," and see what you get.
I think my screen shots are improving too.  This a keyboard feat for me try to hit command, shift, 4 and then move the mouse down far enough to get the desired area in the shot.  This time it took eight tries to get it right.  Practice, practice, practice.  Thanks for indulging me.

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.
