I think I have missed something that everyone thinks is so simple that it doesn't even have to be mentioned. But how do I dive??

I need to know this obviously to do the aquatic form quest.

I can't find any help anywhere. Please help?

Hmm, it's been a while, but if I remember right, you hold the right mouse button and drag down to look down, and then go forward to swim down.

Similarly, to come back up, right click and drag up, then go forward.

I remember wishing there was a keyboard shortcut for that...

Yes, your going to swim where your looking, so just as he said, hold right mouse and left-click to move that direction. Swimming in aquatic form is really handy. It is often used as a getaway tactic versus other classes that are slower in the water. I also recall using it often in places like Stranglethorn vale when your collecting scales and tailfins off the murlocs. 2nd to the undead racial. Thats the best.

i remember someone asking this question in general chat in some noob zone, and everyone just laughed and wouldnt answer him. It seems so simple, but i guess if you dont use your mouse to change which direction you face i could see how it would be less obvious.

freaked me out the first time I died so deep my wisp couldn't rez me from the surface of the water. Took me a while to figure out how to force the wisp underwater.

I had the same problem when I was new, I admit >.>;; It took me like 15 mins to figure it out, was frustrating. What I do is hold down both left and right mouse button and kinda make a swoop motion downward with the mouse, it seems to work all of the time for me now, although there might be an easier way *shrug*
