Few newbie questions.

[Renad]

Greetings. I have a couple questions I was hoping someone could help me with. I would normally use the search option, but for some reason every time I try to access the search feature on my phone, the keypad pops up and then disappears without me being able to type, and unfortunately my phone is my option atm.

So first question. How the heck do I swim?! I nearly drown when I fell in the water, I seem to just sink in place. Is there away to enable mouse look to determine swim direction? I was able to get out by using numpad9, but I was only able to swim up after I hit it, never forward. Any suggestions?
Next one is a simple one, how do you link an item in chat? Lastly, is there a way to display buff timer, or do you just have to guesstimate?

Thanks you for any assistance!
