Camera scaling option while in cam view Blender 2.55 please help

I used to be able to scale the camera view while in camera view by right click selecting the camera frame and then hitting the S key to scale dynamically now its doing something but doesn’t look like its scaling the camera

I think you are talking about zooming in the camera view:
You can do it by pressing G+MMB-Drag
Try also Shift+F. Use W-A-S-D to move the cam like an first person shooter.

Great thanks
knew about the Shift + F
