This will open the Internal viewer, allowing you to include add-ons in the viewed document. When including add-ons, you can use the viewer’s Note and Redact features.

Annotate

Using these tools, you can add various shapes, highlight text, create links to websites, and more. To add a note, press the button of the mark you wish to add. Depending on the tool you choose, you need to press and drag to add a shape anywhere in the document and in the desired size, or select a text block to add a strikethrough.

After adding a note, a context menu appears in the right side of the viewer, allowing you to change the settings for that mark, depending on the type of note you select:

Redact

Watch the video

This feature is very interesting for documents containing sensitive content. More than simply hiding the content visually, the redacted content is safely deleted from the resulting document. The Redact tab offers two different methods: you can draw lock stripes of any size or create lock stripes from the selected text.

Like notes, lock stripes have a context menu that gives you access to settings such as fill color, border color, and the possibility to add text explaining why the content was redacted.
