Well, two things. The first was a success; I downloaded Cream (GUI editor) and added it to the StartUp apps. By dragging that entry (in the StartUp list) to the desktop did produce a working shortcut icon, OK.
Now, I umpinned the LibreOffice Writer from the LH panel and dragged it to the desktop and it disappeared. I have no idea how to get it back either to the panel or to the desktop. Using the method above didn't work probably because I don't know the exact command to use.
There doesn't seem to be a option of starting the launcher directly from the LH panel or Desktop in any case. Why didn't Ubuntu offer a Shortcut option (like Windows?)
