You surely know where your towel is.
In SE docs/ folder there is a scripts.txt file, which is a list of console/script commands. I suppose that a script forward.sc containing something like:
Code
SetSpeed X
Goto Viltvodle VI
Goto Sirius B
Goto Betelgeuze 4
etcetera, and a similar backward.sc script, identical if not for a first line with:
Code
Track Earth
...
Track Viltvodle VI
Goto Sirius B
Track Sirus B
Goto ...
could do something similar to what you want to achieve.
The Track command should point back the camera to the last visited planet, while going to the next.
I should try it myself...
Edit:
well, I thought it was easy, but it's not...
