Quick Cast buttons

[opeth_pa]

Could be that I missed it in the sticky guide but when I edit I see the Quick cast buttons next to the cure buttons. The ones that say Click # 1, Click #2 , so on..

I have a few questions.

1. Lets say my spell name is Malevolent Diatribe VIII the correct line would be usabilityonplayer SELECTED "Malevolent Diatribe VIII" ?

2. Also ..how do i actually use these? its prolly a really a stupid question but assuming its a Click 2 cast time thing?
