How can I add custom commands ( e.g. append to ~filename.txt, send to, send to jon@dearjon.com, not my cup of tea) to the shell's right click context menu? I'm using lxde at the moment and can only find such wizardry connected to file managers (PacmanFM, Nautilus) but this wants to be system wide so I can do this with URL's from browsers and the like.
