Help identifying episode

Hi. I was messaging a friend earlier and managed to amuse/embarrass them so they replied "DEAD" and "I CAN'T TURN OFF CAPS LOCK BECAUSE I AM NOW A GHOST".

So I remind her that even a soft light hologram has a physical light bee and they could shimmy about until they hit the right button.

This is from Red Dwarf, right? Was Rimmer trying to turn off a rogue scutter but couldn't touch it, and Ace reminds him after hilarity ensues that actually yes he could have? I tried to find a clip or anything but came up short. Cheers if you can name it.
