Thanks for your reply. I am aware of the right mouse functionality. This makes affinity basically unusable in a production context. Holding the right and left buttons down at the same time while drawing is unfamiliar and clumsy at best. It works a bit better with the stylus but still clumsy. To replace photoshop i will need to remap the shortcuts. I've noticed Affinity uses many of the standard photoshop shortcuts that we have all committed to muscle memory over the last decades. This was a good idea, unfortunately the designers seemed to have fallen short in one of the most important shortcuts. The best solution here would be to make the shift, ctrl, alt shortcuts the same as photoshop. with some effort I could get used to a different keyboard shortcuts, but right mouse is not going to work.
I see in the preferences-keyboard shortcuts that a shortcut profile can be loaded. I wonder if someone has already created a corrected shortcut profile that i can download instead of having to created it myself. Affnity seems to have gotten some things very right. unfortunately holding the right and left mouse button at the same time is a fail.
thanks
