The Option key has a lot of hidden uses in QuickTime Player, at least when combined with the arrow keys.
Option + Left = Go to beginning
Option + Right = Go to end
Option + Up = Go to maximum volume
Option + Down = Go to minimum volume
Here's where it gets really interesting...
Option + Shift + Up = Go to a louder maximum volume, normally unattainable in QuickTime Player, and impossible to achieve in iTunes (as far as I know).
Other combinations of Shift and Option along with the arrow keys also do various interesting things, some of which may only work in QuickTime Pro.
