7.3. Creating annotations

According to Merriam-Webster’s Online Dictionary, an annotation is a note added by way of comment or explanation. But an annotation in a PDF can be much more. It can be a movie or a sound that will be played in the document. It can be a field with a value that changes depending on other fields. It can be a shape that changes color if you move over it with the mouse.

But let’s not get ahead of ourselves; let’s start with the simplest type of annotation: a text annotation aka a sticky note.
