I needed this for lububntu but it seems to be useful for all.
You will create an entry in /usr/share/applications
the idea is to find simple enough entry (galculator for example)
and use it as a start
copy one simple example and change it using some text editorCode:cd /usr/share/applications
* can be full path to icon image file or system-icon
if someone will answer this http://ubuntuforums.org/showthread.p...9#post12179879 then it will be possible to add new icon mapping
