Ah, you don't have to type literally what I typed, that's just a
shorthand for showing where the osd_cat commandline options would go.
Ignore "OSD_CAT_OPTIONS" and just put the options to osd_cat there.

It is a long document, but then, screen *is* a tiny god.

When you start a screen process, unless you specify a name for it (with
the -S switch, like "screen -S email"), screen will make up a name, like
"10701.pts-13.hostname".  You can now refer to this screen session by
that name.

Screen runs one (or more) processes and makes them think that they're
actually displaying to a real terminal (or xterm), but really, they're
displaying to a fake one that screen keeps track of.  You can "attach"
another xterm to the fake terminal by running "screen -r -x <name>".  If
you had named the screen "email" by running "screen -S email", then you
could open up three xterms and run "screen -r -x email" in each of them.
Then typing into any of the xterms manipulates screen's "fake" terminal,
and all the xterms see the same output.

Anyway, the upshot of all this is that yes, if you close the xterm that
you started screen in, the session is still hanging around, and remind
is still running and piping its output to osd_cat.  It will even keep
hanging around if you restart X (but not if you reboot, obviously).
Running "screen -ls" will list all the currently running screen
sessions.

p.s. if you have any further questions that are screen-specific, I'll be
happy to answer them, but let's take it off-list.  Or even better yet,
I'm also subscribed to screen-users[1], which is an excellent place to
learn more about screen.
