I'm trying to figure out where is 'open in terminal' when right clicking inside a folder? Last time I used it was in Ubuntu 10.10 and since upgrading have no luck with it. I gave up on Unity and using Gnome but still can't find it.
you need install a package named nautilus-open-terminal :
sudo apt-get install nautilus-open-terminal
and restart nautilus:
nautilus -q && sleep 1 && nautilus -n
or logout and login again.
