With the wupdget from this mantis (pastebin) you can "zoom in and out" with 8 and 2 keys on numpad.
There is no checks for limits, meaning you can turn image upside down with negative fov and other funkyness. Also just noticed how uglymeh it is, but for playing it is useless anyway so who cares.
Might allow some new perspectives, for taking screenshots or recording movies.
FOV state is not saved, so if you mess up your camera after restart everything is normal again.
