So this was something I’ve struggled to get my head around in the past, and as it turns out it’s something really very simple!
I wanted to add two new functions to the express keys on my Wacom tablet – flip canvas, and undo.
I opened up the Wacom utility program, added Photoshop to the list of programs, then changed the appropriate express keys to ‘program defined’ but this turned out to be wrong!
All I had to do was select ‘keystroke’ and then enter the appropriate keyboard shortcut, et voila!!!

Let’s see how this helps my work…

In other news, I’d like to give thanks to David Roach for all of his fantastic and invaluable advice and tips on artwork. Also to Dylan Teague. They are both fantastic artists and I only hope I can absorb some of their knowledge through these life drawing classes.
