You're kidding, right? I just told you to use Google, and I even gave you some suggestions about what to search for. I searched for "kde desktop shortcut", and the first result was http://www.tuxist.org/articles/get_k...s_in_line.html
, which seems to have the information you're looking for.
The forums are a great place to get help, but you have to put in some effort here, too, and part of that effort involves you performing your own Google searches.
