When you press a key, the key (Say the "a" key) contains a contact, which completes a circuit. A keyboard is designed for typing, so as soon as the contact is a closed, a single "a" is sent as a signal. However, a long time ago, computer designers quickly discovered that you can be in a situation that the computer will CONTINUOUSLY insert "a" for the duration that the contact is closed. The net result is every time somebody touched a key, they got, no joke, hundreds of "a" because the computer is so much faster than the human hand lifting off the key.To counter this, they programmed all computers to "wait" before putting another letter. This is know as a Typematic Delay, Repeat Delay, or Repeat Rate, and is a few miliseconds. So now, when you press a key, it will wait a few miliseconds between "a".
In context of WoW:
When you press the "a" key, the character turns by one pixel. Then the Typematic Delay kicks in before it moves another pixel. You might say a few milliseconds is not much, up until you factor you have to turn a thousand pixels to change directions, then a few milliseconds between a pixel becomes significant. BTW, when Lore comically turns slowly, this is in fact what he is doing, pausing between turns, which corresponds to a delayed key repeat.
Now a mouse, it was designed to track every motion, up, down, left, right, rotational, whatever. And many mice sport 1200 or 2400 DPI or Dots Per Inch, which means that a mouse "presses the key" 1200 or 2400 times PER INCH of travel. That is why characters move so quick with a mouse, especially if you see how fast it takes for your mouse to travel 1 inch (or 25.4 mm, for us international members).
NOTE:
To all you smarty pants who think you can turn fiddle with Typematic Delayto prove you can keyboard turn as good as a mouse turner, (which, in some BIOSes, you can adjust or reduce to comical values). DON'T! While it would be fantastic for WoW, you will never be able to type anything coherent again, breaking your PC. If you do this, I will laugh at your stupidity and won't be held responsible for it.
