Autorun
From WoWWiki
Autorun is a hotkey. It stands for 'automatic run', which, curiously enough, reflects the nature of the command in that activating it will cause one's character to act as if the player has run engaged.
By default the binding is set to Numlock on the Windows version and Clear (fn-6) on the Mac version.[1]
Alternative Bindings
It is not uncommon for players to rebind this key to something more convenient, such as Shift + W. Often, many skills will be bound to the surrounding keys (Alt and/or Shift ASD, QE, ZXC) in addition to the standard WASD or ↑←↓→ movement controls, meaning one has consolidated much of their button mashing to a single hand.
