I tried the "f" key ...i even tried remapping it but I get no response.
Can anyone get 1st person toggle to work?

"F" works for me...as well as scrolling the mouse wheel.

'F' works for me as well. You have to get past a certain part in the game before you can do it though.

Yes the "F" works now... had to get past the first batch of scenarios. I jumped the gun there.
Thanks for the feedback tho

There is a much simplier way. Simply use the middle scroll button and scroll out it will automatically take you to third person view, scroll all the way back in to go into first person view. Bada Boom.
