In Photoshop and Elements, there are lots of keyboard shortcuts. Maybe you already use a bunch of them. But for me, there was only 1 of them that I used, so this past week I made myself practice using them. Sometimes it truly is hard teaching an old dog new tricks. Especially for me when I'm so used to having the mouse as a permanent attachment to my right hand. It seemed easier for me to just click a few times with my mouse instead of using both hands to do a CTRL letter. Yup, I'm an old dog and I need to get hip with all these new tools!
Here's a listing of keyboard shortcuts for you to experiment with:
For me, the one I learned when I first got Photoshop Elements was CTRL G to clip a paper or photo onto another layer. That one I use all the time. So this past week I tried out CTRL J to duplicate a layer (which I found extremely handy and use all the time now), CTRL Z to undo a mistake (still can't get used to this one since I'm so quick with my mouse to hit that little swirly undo arrow), and CTRL D to deselect when I get the marching ants around an elements when I didn't mean to do that (don't need to do that too often but I like this one). Next week I'll pick out a few more to try. I put them on a post-it on my monitor to remind me to use the shortcuts more often.
So check out the list and see what keyboard shortcuts you're not using and give a few of them a try this week. Let me know how you do!
