3 Choose Custom from the Traversal pop-up menu.
In the Canvas, the first few characters are selected by default, and are affected by the
Scale value.
In the Behaviors Inspector, the Location parameter becomes available.
4 Enable Record (press A).
5 At the frame where you want to begin the animation, drag the Location slider (or use
the value slider) to set where the sequence begins.
As you drag the slider, the selection bars move through the text characters. Values less
than 0% select toward the left of the text (regardless of where the anchor point is);
values greater than 100% select from the beginning of the text toward the right.
When Traversal is set to Custom,
the Location parameter
becomes available. Use the
Location slider to keyframe how
the sequence moves through
the text.
