I want to set my mission control shortcut to my mouse secondary button. However, under mission control shortcuts, the second column isn't displaying. Any idea how to fix this?
I've read that the second column doesn't display depending on the mouse or trackpad being used. I'm using a Magic Mouse and have it setup on other macbooks, so I really can't understand why it's not displaying for me. I'm using a 2015 MacBook Pro with 10.12.2.
MacBook Pro with Retina display, macOS Sierra (10.12.2)
