within range and uses the ability. Click to move is a useful option, but keep in mind
that it also means your character will move automatically at the slightest right-click
of the mouse.
Abilities That Require a Target
Some abilities require that you select a target after you click on them and before
they occur. For example, for an Arcane Intellect spell, you would need to click on
the Arcane Intellect icon on your action bar (or press the appropriate hotkey), then
click on the target, and then your spell would be cast.
If this is the case, your hand cursor will glow, indicating that you must choose a
target. A bright glow tells you that the target you are clicking on is legal. A dull
glow indicates that you must find a new target.
Logging Out of the Game
To end your session in World of Warcraft, you can click on the Log Out or Quit
buttons from the main menu. If you click on the Log Out button, a log out box
appears in the middle of the screen. A 20-second timer in the log out box counts
down to zero, at which point you are logged out of the game. To cancel your log
out, press the cancel button. If you log out of the game while in an inn or one of
the six capital cities, you log out immediately without a wait. When you click on
the Quit button, you get a similar box and options. However, logging out takes you
back to the Character Selections screen, while quitting closes the game and takes
you to the desktop.
