Modify Gnome Menu

Well~ The most convenient way I think is to use alacarte:

$ sudo yum install alacarte

Then just type in

$ alacarte

Alacarte will run as a GUI, simply choose what you want:-)

There was a large amount of information that introduced where the gnome items in menu were saved in. However, I don't know whether the authors have examined the content they say, or there has been huge changes on gnome menu, the result is I cannot find the corresponded location... So why not use a simple GUI to solve the problem?
