Here is the first tutorial! It's something simple, but I promise there will be more complicated stuff to come. You just have to work with me for now. I've got tons of stuff in the archives but I don't want to shell it all out for you at one time! What fun would that be?
Ctrl + Z = UNDO (My personal favorite.)
Ctrl + D = Hide Selection or Show Selection
Ctrl + A = Select All
Ctrl + Y = REDO
Have fun with the your photo editing and good luck!
