I know the route command, but I can't really see how I will p ...

I have installed the selektor and tried to use the below part of this instruction.

You will then be able to use Tor (via Privoxy) as a regular HTTP proxy. To do this, install Privoxy:

Then, edit the Privoxy configuration file as root (I’ll use Gedit below):

gksu gedit /etc/privoxy/config

… and add this at the end of the file:
