I'm trying to learn about the Skin modifier- you can press a button to get a vertex to act as a root, but is there a button to reverse this? Is a given vertex just going to be a root forever?
The default Blender navigation is easy to get used to, my Pen is set to have the bottom button as MMB and the other one as RMB. With the clicking of the pen on the tablet as LMB you have all your mouse buttons on your hand. I use this configuration with all the applications.
