I am experimenting with Gimp 2.6 for Windows. I am doing quite well, I can choose different brushes and resize them easily enough, what I haven't figured out is how to easily edit the brush softness as I am working. In Photoshop I would simply choose Shift + left/right bracket. How do I do the same thing in Gimp please, its driving me nuts so any advice appreciated! I have tried to research this on the web myself, but just can't find the answer.
