Assuming the default settings for the system is the desktop, you can get
back simply by pressing the RETURN key on a line by itself (no spaces,
etc).
You can see the system settings by typing *status.  You can set them with
*configure.  You can see the environment settings (which mostly also apply
to the desktop) with *show.  You can set them with *configure.  You can
enter BASIC from the command line with *BASIC. And so on...  All of these
commands accept abbreviations, eg *sh. for *show.  They're not
case-sensitive, by the way.
