By the way, these special spells can be manually put on any bar if you like, because you can simply find their spellID and run it trough PickupSpell(spellID) then place the spell on the bar -tada!
Not much point except it being visible on the screen, unlike a hotkey would use the spell but not be visible on your bars (if you hide the extra bar).
Anyway, not really on topic, sorry!
