You can put this macro on an Alias or Keyboard shortcut to toggle SubD Wires in current display mode (all in one line):
SetRedrawOff -_RunScript (Call Rhino.ViewDisplayModeProperty(Rhino.ViewDisplayModeEx(), "Objects\SubD\SmoothVisible", Not Rhino.ViewDisplayModeProperty(Rhino.ViewDisplayModeEx(), "Objects\SubD\SmoothVisible")) ) SetRedrawOn
If you need to add the other two, maybe you can figure it out based on the info it this topic:
