How do you pan around a cab and see and access the various controls? Is this possible only on some DLCs like the AP one, such as this and not the standard trains? I've looked through the manuals, both the TS2021 and AP ones, but can't see anyway to pan around the cab, see all the controls, side panels, windows: the keyboard arrows just move driver seating position or show a rear view. It would certainly be more interesting to see each train's controls and familiarise myself with how to use them, instead of relying on the generic HUD controls and keyboard commands. One last question on viewing - I have been able to use the arrow keys to move around the outside in "helicopter" view, but how do you change the height of the view, as I've seen in some videos?
Press CTRL and then use up and down cursor keys. Remember view 2 is locked to the train, and view 8 isn't, so CTRL + up and down will have different effects for each view.
