Editing PDFs
Last updated 1/14/2015
In Acrobat, if the content that you edit or delete is associated with one layer, the content of the layer reflects the change.
If the content that you edit or delete is associated with more than one layer, the content in all the layers reflects the
change. For example, if you want to change a title and byline that appear on the same line on the first page of a
document, and the title and byline are on two different visible layers, editing the content on one layer changes the
content on both layers.
You can add content, such as review comments, stamps, or form fields, to layered documents just as you would to any
other PDF document. However, the content is not added to a specific layer, even if that layer is selected when the
content is added. Rather, the content is added to the entire document.
In Acrobat, you can use the Merge Files Into A Single PDF command to combine PDF documents that contain layers.
The layers for each document are grouped under a separate heading in the Layers panel of the navigation pane. You
expand and collapse the group by clicking the icon in the title bar for the group.

About articles
Many traditional print documents, such as magazines and newspapers, arrange text in multiple columns. Stories flow
from column to column and sometimes across several pages. While the format is effective for printed material, this type
of structure can be difficult to follow on-screen because of the scrolling and zooming required.
The article feature enables you to guide readers through material presented in multiple columns and across a series of
pages.
Define articles
You create an article by defining a series of boxes around the content in the order in which you want the content read.
The navigational path you define for an article is known as the article thread. You create a thread connecting the various
boxes, unifying them into a continuous text flow.
