Let me try to express my question a little better (and more accurately):
1. In Add/Remove Applications I can see all installed applications, including these two, for example: "gedit" and "GNOME Desktop Utilities".
2. Neither of these two shows up when I click Start/Accessories, or any other category of applications (Science, Internet, Office, etc.). So I go to System Settings/Main Menu, and try to find them there to check the box in front of them. But they're not listed there, so there is no box to check, like there is with some other applications, so I can't make them appear on the list of applications under Accessories or one of the other categories.
3. So how do I start such applications? I know I can start gedit by opening a text file, but there has to be a simple way to start any of the applications appearing in the Add/Remove Applications list. It would be nice to be able to start them by double-clicking them on the Add/Remove Applications list...
