Apple Motion 4 - Manual (Page 141)

Value Field
This control allows direct entry of text to set the value of the parameter.
An example of a parameter that uses a value field is the text entry field.
Activation Checkbox
Any parameter that must either be on or off uses a checkbox control. For example, the
All Caps and Align to Path settings for text objects are controlled with checkboxes.
Unlike those with sliders and dials, parameters controlled by a checkbox cannot be
keyframed.
To activate or deactivate a parameter controlled by a checkbox
µ
Click the checkbox.
Menus
Motion uses a variety of different types 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 pre-defined set of options are controlled with pop-up menus. In
some cases the choices available in the pop-up menu might change depending on the
settings of other related parameters.
To change the value of a pop-up menu
µ
Click the menu and choose an item from the list.
The menu displays the name of the selected option.
