Document Toolbar
By default, the Document toolbar contains tools for manipulating document content.
Note: The exact tools a user will see depends on their Profile, licensing, and the customizations they have made and might not include all the tools mentioned here.
The toolbar may be hidden, and you can unhide it by following the steps in the Show / Hide Toolbars article. Below is an image of the toolbar.
Headers and Footers: Click the main button to open the Header and Footer dialog box, from which you can add a new header and/or footer (if none currently exist on the page) or edit the current header and/or footer. Click the arrow to the right to invoke the Headers & Footers menu.
Add: Adds a new header and/or footer to the document.
Edit: Edits the document's existing header and/or footer.
Crop Pages (SHIFT+ALT+O): Crops the page to remove unwanted content.
Flatten (CTRL+SHIFT+M): Flattens markups in the current document, moving them from the markup stream into the main body of the PDF, rendering them uneditable.
Erase Content: Removes text, vectors, and images from documents.
