I don't know the appropriate command, nor the "codename" of the application. I want AltGr+F to start the system-wide file search utility that is shown at the bottom of the Places menu in the top panel.
After clicking on "Search for Files", the search window that appears has a title bar at the top that says "Catfish";
catfish (lower-case) then is the command/"codename" for the Catfish search application. You can test such things by pressing F12 to bring down the Guake terminal and then type in your guess to see if it launches your desired program.

I'd like the app finder to be just <super> instead of <super>+r, but I don't see a way to change that.
The <super> key is a metakey (like the <Shift> key); if you could somehow make just the <super> key launch an application then the <super> key would cease to function as a metakey; as such, there is no option to make just the <super> key alone launch anything. (You could in theory write your own C code to make the <super> key do whatever you want, but that would take years worth of C programming classes to learn how to do.)
