The only way to move around in orbit is to use SLEW.

In the FLIGHT MANUAL Part I – User’s Manual, page 6, it says:

Using SLEW mode controls it is possible to orbit the Earth and perform various in-orbit operations.

Note:
MS FS animations do not work in SLEW mode. Temporary switch SLEW mode OFF to control animated systems.

So reading the manuals is very helpful.
