There is no cheat list available. What I wrote is for a *non-interactive
automated* graceful shutdown of the application. If you want something
like that then you will have to research each application that you use
frequently and/or care about, and determine what command will do such a
graceful shutdown.
Otherwise, as raster mentioned, use e17 and be prepared to be prompted
for more time to logout everytime some app doesn't want to quit. And
then you will again have to "continue scrolling through my virtual
desktops, shutting things down"!! :-)
