Hold down right key for specified time in front row to fast forward

Is there a way to hold down a keystroke or keycode so that front row recognizes the command for a specified amount of time.
Front row has the ability to fast forward 1x,2x, and 3x. All three are recognized by the amount of time you hold the right arrow down for.

tell application "System Events"
	key code 123 -- cursor right
--hold for 1 second?
