The Annotation feature in Slidea allows presenters to highlight, draw, and explain content during a live presentation. It is used to emphasize key points, direct audience attention, and visually support explanations without modifying the original slide design.

This feature is accessed only during a live presentation and can be enabled to highlight slides in real time while speaking.

How to Access the Annotation Tools

You can access the Annotation option in the following ways:

Option 1:

On the presenter screen, select the annotation icon at the bottom-left corner, and the annotation toolbar will be displayed.

Once enabled, a vertical editing toolbar will appear on the presenter screen.
