Manual

Latency Bar: Measures the speed of your connection to the World of Warcraft server. A
green bar means your connection is good. A yellow bar means you may
experience intermittent delay, called lag. A red bar means your connection is
poor and you will experience significant delay.
Name: The name of your selected target. A tag underneath a name might be a
player's guild affiliation.
Rest Marker: Shows your rest state. In rested state, you earn 200 percent of
experience from kills. In normal state, you earn 100 percent of experience. Rest
state does not affect quest or exploration experience.
Selection Circle: This circle appears around a target when you select it. The color of
the circle indicates hostility. Red = Aggressive. Yellow = Passive until you attack.
Green = Non-combatant.
Tool Tip: This appears when you click on or mouse over a creature or character.
Inside is the target's name, level, and class or type. The color of the tool tip
indicates hostility. Aggressive targets are red, passive targets that fights when
struck first are yellow, non-hostile targets that cannot be attacked are green, and
player characters are white.
Minimap: A miniature map of your character's surroundings.
You can zoom the view in or out using the plus and minus keys.
The name of your current zone or location appears above the
minimap. Towns appear on the edge of the minimap as arrows,
while party members, pets, and resource nodes appear as dots
within the minimap.
Smart Cursor: When your mouse cursor moves over an object
or character that you can interact with, it changes shape to reflect a new action you
can perform. See page 44 for more info.
Status Icons: Any positive conditions, or buffs, affecting your character appear here.
Most buffs are cast on you by yourself, friendly players, or NPCs.
Target Portrait: Shows the name, face, and health bar of any creature or character
you click on in the game. Depending on the target, it might also have a mana, rage,
or energy bar.
