Hey thanks, I was able to get the navigation controls to how i like them, replacing the brush radius and depth RMB command. But now i'm trying to assign that radius/depth thing to another keyboard command (shift+alt+RMB, since that's what my secondary Stylus button is mapped to). In that same menu you mentioned, i assigned "start tweak radius and depth"" to shift+alt+RMB like I wanted, but when i perform the action it still just moves around screen space. I've looked through that menu to see if "move in screenspace" is still assigned to shiftaltRMB, but it isnt. I have no idea why it's still performing that when I press my button. Any ideas?
