* Pressing Shift + B opens up all of your packs. Makes selling easier. You can also shift-click any bag in the toolbar to open/close them all.

* Holding down Alt causes you to select yourself as the target for spells, buffs, etc. F1 does this as well. F2-F5 selects your fellow party members. If they have a pet, hitting their F key twice will select the pet.

* Be sure to log out inside of an Inn or major town to build up your rest bonus. This bonus is determined by how long you are in the rest area (capital cities count in their enterity) and caps at approximately 1.5 levels worth of xp doubling which takes about 2 weeks in a rest area to hit.
This time accrues whether you are logged in or not so ALWAYS log in an inn or capital city.

* Shift + Right click to auto loot kills, crafting nodes, chests, and any world object that can be manipulated.

* Shift + Left Click either posts an item into the chat window as a link if you have chat open, or it splits a stack of items. This can also be used to select how many of a non-stacked item you want to buy from a vendor.

* With a teammate targeted, typing /assist will fight what they target. In the default configuration, "F" will select their target. If you're running a pet, F1-F1-F will select whatever your pet is aggro'd on.

* Not so much at trick, but faction discounts apply to the flyers and trainers as well, so don't be so quick to throw away newbie quests that you forget to complete - they help out in the long run. Be aware that the reputation received from a quest drops off sharply when it goes grey, unless the quest is a high-profile one for that faction (i.e. Defias for Stormwind). Also, many quests give reputation bonuses in more than one faction; you see this a lot with Ironforge/Gnomeregan Exiles. Finally, if you hover over a quest-giving NPC, the game now tells you in the tooltiip which faction they're aligned with.

* The command /random # # makes dice rolls between the two numbers specified (ex: /random 1 100 will roll randomly (1-100)). It's useful for quests and such, as I always use it to roll for chests or veins of ore, etc.

* Go Swimming There are often chests at the bottom of lakes as well as mineral nodes that won't show up on radar until you are submerged. (the lake outside Loch Modan (sp) is Amazing for tier 1 and has 5 chest spawns that I have found so far)

* Increase the range of your "Target nearest" key. Go into your WTF folder and edit the Config.wtf file. Add the following line at the bottom:

SET TargetNearestDistance "40.000000"

* The Auction House will respond to you much quicker if you narrow your search range. If nothing else, use the level range boxes, and search by armor/weapon category. Also, using the text-string search box is the fastest way I've found to find consumables.

* <Armor> of the <Animal>: These are paired stat bonuses based on the animal type, and they will always have the same two stats paired. If you're looking for stat buffing armor, and you know what stats you want, search Auction House for the following animals:

Bear: Strength, Stamina (Warrior, Paladin)
Boar: Strength, Spirit (Decent for Troll Warriors (higher regen))
Eagle: Intellect, Stamina (Mage, Warlock, Priest)
Falcon: Intellect, Agility (Druid, Shaman)
Gorilla: Strength, Intellect (Druid, Shaman)
Monkey: Agility, Stamina (Hunter, Rogue)
Owl: Intellect, Spirit (Mage, Warlock, Priest)
Tiger: Strength, Agility (Decent for non-magic classes)
Whale: Spirit, Stamina (Maybe for a weird-build Pally...)
Wolf: Agility, Spirit (Hunter that wants mana back faster)

* To make fast cash when you're really bored, farm -5/-6 humanoid creatures. They drop Linen/Wool/Silk, all of which sell very well in AH if you put low buyouts. They also drop more copper/silver than comparable beasts, demons, dragonkin, or elementals.

* Mobs turn grey (no experience) at -7.

* Cooked food stacks to higher amounts than raw food. By training cooking, you can double a single slot's worth of storage, and get more benefit.

*While on autorun, hold down the right mouse button to steer. Easier to make small course corrections this way.

*If you train a new weapon skill, head to SW Tram station. Deeprun Rats spawn as fast as you can kill them in one corner of the station. I went from 20 - 60 skill in about 15 min.
