I just downloaded Affinity this afternoon and after spending some time watching tutorials I felt confident enough to jump in and get to work on some photos. I'm working on my laptop macbook pro and I don't have a mouse so I'm using my track pad.
I've selected to use the inpainting brush tool and have the width of the brush set, but when I press the track pad down with my thumb and then use my index finger to navigate the brush it doesn't seem to "activate" the tool. The circle for the brush just moves around wherever I move my index finger. Is there some other step I've missed or is there some other way to "drag" when using a track pad?
