New player with a stupid question....How do I list things on the Auction House? Just got the game on Steam and am having a blast so far (I come from ArcheAge).

My bag is full and I want to sell some of the herbs I have. I figured out how to open the auction house (click escape and then auction house), but have no idea how to list anything. Right clicking items in my bag does nothing and there is no place/box in the Auction House to drop them in.

Any help is greatly appreciated. I think I am level 12 or 13.
