When I attempt to add a node, the shortcut keys never work. When I'm attempting to assign keys, if I hold down "CTRL-ALT-1", nothing happens. If I manually type Ctrl+Alt+1, it's accepted, but then pressing CTRL+ALT+1 doesn't bring me to that node - or do anything, for that matter. Am I doing something wrong?
It doesn't work on MM3 because some internal script handling (and error handling) has been changed.
As it is now I don't think it's possible to make the script work for MM3. I'll take a good look and ask the MM devs for a re-solution.
