An object menu, also called a pop-up menu, is displayed when the user
clicks on a GUI object with the right mouse button. These menus contain items
specific for the current activity, and most are duplicate functions of main menu
items.
Experienced users may be irritated by nested menus. They may prefer to use a
single-line command entry to speed things up. Other users might use the shortcut
abbreviations or key combinations such as Alt > I > P > C, which inserts a picture
that is clip art in a Microsoft Office document.
