When I press Ubuntu button (former Windows button) on my keyboard and start typing application name I want to launch, I see there 2 instances of the same programm (in my case it's PyCharm IDE). I have checked my /usr/share/applications (it's having only the one PyCharm.desktop) and ~/Desktop folders (doesn't have anything).
I suspect I created somehow somewhere the .desktop shortcut for older version of PyCharm, which I'm not using anymore. The problem is I don't remember where and how I did it. And Ubuntu launcher isn't telling me from where program shortcut came from to my search results. So I can't get rid of this second instance of PyCharm shortcut.
Could someone please send me to the webpage which explains ALL places Unity Launcher uses to find applications? Any other help would be appreciated. I'm using Ubuntu 13.04.
