How do you change the radius of the brush in the UV editor for grabbing UVs. All I've found is F and Shift-F but, it doesn't change the UV brush radius.
I just answered my own question. You tap the F key or, hold Shift and tap F.
This may seem really obvious but, I am coming from using the brush in Autodesk Mudbox where the keys are B and M and you just hold them down.
