I only know of a couple more:
1 sets the camera to the default isometric view
2 sets the camera to a zoomed in topdown view
3 sets the camera to a zoomed out topdown view (further out than 1, but not quite as far as the clothmap)
4 sets the camera to a topdown view on the clothmap
5 sets the camera to a zoomed in isometric view
Ctrl + n creates a new map, using the same parameters as before
Ctrl + tab brings up the Reactor overlay (this allows you the check your achievements, chat, and other things, if you are logged in)
