Menus
Motion uses a variety of menus and menu-like controls. These include pop-up menus, value lists, parameter selection menus, and tracking selection menus.
Menus cannot be keyframed.
Pop-Up Menu
Parameters that have a predefined set of options are controlled with pop-up menus. In some cases the choices available in the pop-up menu change depending on the settings of other related parameters. Several varieties of pop-up menus appear throughout the Motion interface, but they function identically.
Click the menu and choose an item from the list.
Parameter Selection Menu
The parameter selection menu is a special type of pop-up menu, specifically for Parameter behaviors. Usually labeled “Apply To,” the parameter selection menu appears in the Behaviors Inspector after you apply a Parameter behavior. The menu consists of a display field listing the parameter that the behavior is modifying and a To pop-up menu from which you can choose a different target parameter.
