Kun-lai Summit: At the Yak Wash, use spells while on a yak

[chronux]

If you get to the quest At the Yak Wash, you need to jump on a yak and go through the washing place. Your action bar will be replaced with the vehicle bar, with one 6sec CD spell to increase speed by 100% for 6 seconds.

However, if you open your spellbook, you can still use attacks & spells.. Even while running!
I have no idea if it could be done easier without needing to open the spellbook & scroll through the pages to use multiple spells you often or situationally use.

You can't move away from the quest zone too far or it'll teleport you back near the questgiver.

Always fun to duel some melee players around the area & kite their ass. May serve for some other things aswell (hint ;D)
