saved as PDF (Portable Document Format) files, for example, in the
OpenOffice.org suite. View them with Okular, the default KDE document

Apart from PDF files, Okular allows you to view a great number of file
formats, such as PostScript, several image formats, OpenDocument format
(ODF), OpenDocument text (ODT), some eBook formats (ePub), and even

Working with Bookmarks and Annotations
With Okular, you can review a document by highlighting certain text

the file in form of metadata. Note that the annotations and markers
you add are not stored within the document, so you cannot print them
or pass them on to other users.

main display field and press Ctrl+B. The page is added to the
list on the left sidebar. Right-click

bookmark or renaming, or removing it.
To create an annotation for a page, press F6 and
select one of the annotation tools from the toolbar that appears. The
annotation is added to the list of and is
flagged with the login name of the user who created it. Use the icons
at the bottom of the sidebar to group the annotations by page, by
author or to show the annotations for the current page only.
To open a pop-up note and add text for an annotation (or to remove an
annotation), right-click the annotation entry in the
list and select the respective menu item.
