Running Platform Version 4.12.5 on FreeBSD-10, I accidentally hit the "WIN"
key and the "S" key simultaneously. I immediately lost my desktop. How do I=
 go
about getting it back. I really do not want to have to recreate all of those
icons I had placed there, etcetera manually. I cannot seem to find any thing
on this via Google.
