Typing text on a document
The Typewriter tool allows you to add typed annotations to a document. This does not allow you to alter the original text of a document; it just allows you to add typed text. Text boxes can be placed and resized, and edited later.
You can change the font size, color, and opacity of the text.
Editing a typewriter annotation
After the Typewriter tool has been dismissed, you may edit the annotation to change the font size, color, and opacity, the text of the annotation, and the size of the text box.
