Many of you probably use the hotkeys on the action bar to fire off attacks and abilities. Since you use the WASD keys to move, it's really easy to use the 1-5 keys for quick abilities. I'm sure most of you already know about how you can drag skills from your spellbook and drop them into the bar to arrange the keys. What I didn't learn for a long time is that you can hold down the shift key and roll your mousewheel up or down to switch between multiple action bars. This way you can set up 1-5 skills on the first bar, shift mousewheel, and use skills 1-5 on bar 2. I used this to set up attacks on the first bar and heals/buffs on the second. Having those extra 5 skills with instant access gives you a real edge in the game.
