Ok, maybe you are aware of these shortcuts but I'll put them up here just in-case you haven't discovered them:

- Ctrl + End This will save your current camera position. The camera will default to this when you mount or enter a zone

- Ctrl + lshift + End This clears your saved camera position and puts it back to default

- Ctrl + Direction Keys (Up and down) This changes the camera tilt angle

Hope that was some use.
