[Gimp-user] changing the brush sizes

[mehjg <forums gimpusers com>]

I want to be able to edit my brushes and save them, using the appropriate dialog
box, but no matter what I do, the size doesn't change. I can change the
hardness, angle, aspect ratio, etc., but the size just won't change, whether
using the bracket keys or the radius slider. I'm not using a mouse and I don't
want to try using the track pad's scroll function to change the size of the
brush because I use it to scroll. Any suggestions?
Thanks,
Matthew
