That's part 2 of a question asked earlier (to be able to give credit to the answers individually).

When I type into the Dash applications show up with their title (also when hovering over the launcher), how can I find the associated desktop file. When I look into the usual suspect locations (/usr/share/applications and ~/.local/share/applications) with Nautilus I see the titles, but not the file names (not even in properties which sucks). When I look from the command line I see the file names but not the titles (a switch would be nice).

How can I get a listing (a custom column?) that shows them next to each other?
