@CypherPoet fair! Though I’ll be honest… That was a real long time ago and I ended up forcing myself to get used to the OS Key instead and freeing up my option key. Far too many uses for opt in Blender and I was missing them all. Particularly in rigging. I think that’s when I decided I had to get used to it.
So both work, but a year later I changed my mind: OS key for the win.
