i would like to customize applications menu (right mouse button), change same application path or name and change the language (from english to italian, as for the applications, these already in Italian).
Where should I start? :-)
obmenu is the command you want for a gui app to modify the menu. It should be on the default menu in the customize openbox section. If it's not there, "obmenu" in a terminal will start it up.

You can also just open .config/openbox/menu.xml in an editor.
