Ah, you are using a cycle command interface?
If that's the case then, you could add an if query into the right mouse button actions (where I mentioned earlier).
I'll write it in Lua script as I'm not in the right frame of mind to wrap my head around if queries in the editor itself. Easier with Lua anyway.
1. create an execute a script action inside of the right mouse button actions under the game > mouse properties tab.
2. insert this into it...
if game.ActiveCommand:getName() == "funcur-base" then
game.ActiveCommand = Buttons["funcur-look"]
game.ActiveCommand = Buttons["funcur-base"]
... basically we are checking on right click if the active command is the base command then set it as look else reset back to base command.
