Scroll Text controls in Motion

Use the parameter controls in the Behaviors Inspector to adjust the direction, rate, and position of the scroll:

Scroll Direction: A pop-up menu to set the direction of the text scroll to Vertical or Horizontal.
Speed Control: A pop-up menu to set the speed of the scroll or crawl. There are three options:
- Automatic: The speed of the scroll is determined by the length of the behavior in the Timeline. In other words, the length of the behavior determines how long it takes the object to scroll or crawl across the canvas. By default, the duration of an applied Scroll Text behavior is the same as the object or group to which it is applied.
- Fixed: The speed of the scroll is based on the value in the Scroll Rate parameter (described below).
- Custom: Specifies the start and end positions (defined as offsets from the current position) of the scrolling object.
Scroll Rate Mult: A slider (available when Speed Control is set to Automatic) to multiply the rate of the scroll. Amounts higher than those available in the slider can be entered in the value slider (the number field to the right of the slider).
Scroll Rate: A slider (available when Speed Control is set to Fixed) to set the speed of the scroll in pixels per second.
Reduce Flicker: A pop-up menu to modify the speed of the scroll to reduce flickering on interlaced or progressive displays. The menu options vary, depending other parameter settings:
- None: Available when Scroll Direction is set to Vertical, this option has no effect on the speed of the scroll.
- Progressive: Available when Scroll Direction is set to Vertical, this option prevents flicker on a progressive display (such as an LCD television). The Progressive setting is not guaranteed to prevent flicker on an interlaced display (such as a CRT television).
- Interlaced: Available when Scroll Direction is set to Vertical, this option prevents flicker on a progressive display (such as an LCD television) or on an interlaced display (such as a CRT television).
  Note: Because the minimum speed to prevent flicker on an interlaced display is 2 pixels per frame, and the minimum speed to prevent flicker on a progressive display is 1 pixel per frame, the Interlaced option may result in faster scroll rates.
- No: Available when Scroll Direction is set to Horizontal, this option does not modify the scroll speed to reduce flickering on interlaced or progressive displays.
- Yes: Available when Scroll Direction is set to Horizontal, this option modifies the speed of the scroll to reduce flickering on interlaced or progressive displays.
Allow Layout Override: A checkbox that, when selected, permits manual changes to the layout method (set in the Layout Method pop-up menu in the Layout pane of the Text Inspector). For example, when you apply the Scroll Text behavior to RTF text and set Scroll Direction to Horizontal, the text is placed in a single line. If you select the Allow Layout Override checkbox, the text retains its paragraph format.
Note: This parameter is available only when the Scroll Text behavior is applied to a text object.
Start Off-Screen: A checkbox that, when selected, moves the text to an off-canvas position for the start of the scroll.
