Today, I learned how to use a new cash register. The woman who taught me the basics is 94 years old and believe me, I paid attention. Learning is so much fun.
I learned a few more new things about photoshop too. Here is a useful Photoshop article, "28 More Exceptionally Useful Photoshop Shortcuts." I constantly use the Ctrl A (select all), Ctrl D (deselect) and Ctrl T (transform) commands - really saves time. Enjoy!
