Apple Motion 4 - Manual (Page 879)

Allow Layout Override: Allows the text layout be manually changed. For example, when
horizontally scrolling imported RTF text, the text is automatically placed in a single line.
If the Allow Layout Override checkbox is selected, the text retains its paragraph form.
Note: This parameter is available only when the Scroll Text behavior is applied to a text
layer.
Start Off-Screen: When this checkbox is selected, the text is automatically moved to an
off-Canvas position for the start of the scroll.
Text Tracking Behavior
The Text Tracking behavior applies rate of change to the Tracking parameter of the Format
pane (in the Text Inspector). Tracking applies a uniform space between each character
of text.
To use the Text Tracking behavior
µ
Apply the Text Tracking behavior (from the Text Animation subcategory) to the text.
By default, a Tracking rate of 10% is applied to the text.
As the project plays, the characters spread out based on the rate set in the Rate parameter
of the Text Tracking behavior.
Note: Just like the Tracking parameter in the Format pane of the Text Inspector, the Text
Tracking behavior respects the Alignment setting of the text. For example, to track from
the center of the text outward, the Alignment of the text must be set to Center. This
parameter is located in the text HUD or the Layout pane of the Text Inspector.
