Not supported by TWC

Property icon The Navigator supports the following properties, which are available via the Properties pane and the Canvas script editor. Click next to any property name in the Properties pane to see a short description for the selected property.

See Accessing Screen Objects for more information about how to view control objects in script in the Canvas application.

Categorizing, Sorting, and Finding Properties

You can click (Categorize), click Alphabetize (Alphabetical within Category) or click (Search) within the properties using the features located immediately above the properties list. The search box is useful to help locate a property when an object contains many properties. For clarity, when you enter a search term, items matching your entry string remain displayed and non-matching items are temporarily hidden. Clear the search box to display the full properties list again.

You can expand and collapse each property category by clicking Down arrow or Up arrow next to the group name or simply clicking anywhere in the category heading.
