Well, I know it will take time, but I haven't seen anyone else °use° this system.
Mind you, I don't use it °very° often myself. I can understand that it's not easy to type, there being no specific ° key. How I get around it is I have it programmed into Shortkeys Lite, so all I have to do is type z and x and I get °.
The other way would be to use Alt+ 0176, like this °.
