Documentation:
Typewriter

Typewriters can trigger multiple typewriters to type when they finish.

In the typewriters that you wish to BE triggered:

1. Set the Trigger setting to Start typing when triggered.
2. Enter a unique identifier for the typewriter into the Trigger ID field. (eg. Typewriter-B)

In the typewriter that you wish to DO the triggering:

1. Set the Trigger setting to Start typing immediately or Start typing when visible.
2. Enter a comma separated list of Trigger IDs for the typewriters you wish to trigger into the Trigger Others field. (eg. Typewriter-B, Typewriter-C, etc…)

In the example shown here, Typewriter-A will start typing when it becomes visible on the page. Typewriter-B and Typewriter-C will then start typing when Typewriter-A finishes.

See here for another example.
