If I didn't know the command for a specific application, it used to be possible to create a desktop shortcut, then look at the properties. This was handy, for example, if I wanted to add a programme to the "Startup applications" list.
With Unity, that option is gone, and I have to log out and log bank in with the "Classsic" desktop to repeat the procedure. Presumably I won't be able to do even that after 10.10, so is there a better way?
You are making your experience way to difficult! Have a look at the system settings menu (->choose log out -> system settings at the bottom):
and click 'main menu'
You can also get there this way:
and there is your good old menu:
Open the Main Menu program.
Select your application of choice
Click Properties on the right to reveal/edit everything you want to know about the launcher.
