Is there any way to quick switch between first and third person perspective in skyrim?

I'm looking for a way to quickly switch between first and third person perspective in skyrim. I've learnt that you can press the F key and this will switch, but there is a delay, is there anyway to speed this up, or swap instantly?

You can speed up the transition speed between first person and third person by adding the following lines to your Skyrim.ini file under the [Camera] section:

fMouseWheelZoomSpeed=60.0000
f1st3rdSwitchDelay=0.9500
iHorseTransitionMillis=001 

This will affect changing perspective both by using the keyboard binding (default F) and the mouse wheel.

The Skyrim.ini file should be located in %USERPROFILE%\Documents\My Games\Skyrim rather than in the steamapps folder, if the file doesn't exist you should simply be able to create a file named Skyrim.ini in this location.
