First Im new to this and I did try a search. Recently purchased a Surface Laptop Studio. I needed a new laptop and this one with the ability to fold flat over the keyboard and use as a tablet is perfect. This is my first tablet though. Basic question ... When I'm in tablet mode, folded flat over the keyboard, when drawing a shape I cant figure out how to constrain proportions without popping the screen up and reaching in to try and hit the shift key, very cumbersome. There doesn't seem to be a way to program my surface pen to use one of the buttons as a shift key. Sorry if this is a silly question for the pros, am I missing something simple, or is constraining without shift impossible? Forgot to add I am using V2 of all the Affinity Apps.
Thanks, Mark
