<title>Introduction</title>
<para>&okular; is a &kde; universal document viewer based on the code of the &kpdf; application.
Although being based on &kpdf; code, &okular; has some unique features such as overview mode,
improved presentation support and annotation support.
</para>
<!--
<para>
The PDF format is widely used for publishing documents that are
mostly not meant to be edited again. &okular; is only a viewer
for these files and therefore it doesn't provide any functionality
to edit or create PDF documents.
</para>

<chapter id="use">
<title>Basic Usage</title>
<sect1 id="opening">
<title>Opening Files</title>
<para>
To view any supported file in &okular;, select <menuchoice><guimenu>File</guimenu><guimenuitem>Open...
</guimenuitem></menuchoice>, choose a supported file in the dialogue and click <guibutton>Open</guibutton>.
Your file should now be displayed in the main window.
</para>
<para>
If you have already opened files in &okular; before, you can quickly access them by selecting them in
the <menuchoice><guimenu>File</guimenu><guisubmenu>Open Recent</guisubmenu></menuchoice> menu.
</para>
<para>
After having a file opened you probably want to read it and therefore navigate through it. Go to the
<link linkend="navigating">next section</link> to learn more about this.
</para>
</sect1>
<sect1 id="navigating">
<title>Navigating</title>
<para>This section describes how you can navigate through a document in &okular;.</para>
<para>
There are multiple ways of scrolling the viewing area. One is to use the
<keycap>Up Arrow</keycap> and <keycap>Down Arrow</keycap> keys. You may also use
the scrollbar, your <!--TODO: insert entity, if any-->mousewheel or the <keycap>Page Up</keycap> and <keycap>Page Down</keycap>
keys.
</para>
<para>
Another way is to hold the &LMB; down at any place on the document while dragging the mouse in the
opposite direction of where you want to move. This procedure only works if the Browse Tool is
enabled, which you can select by choosing <menuchoice><guimenu>Tools</guimenu><guimenuitem>Browse Tool
</guimenuitem></menuchoice>.
</para>
<para>
The navigation panel on the left side of the screen enables two more ways of navigating
through a document:
</para>
<itemizedlist>
<listitem>
<para>
If you click on a page thumbnail the viewing area will be brought to
that page.
</para>
</listitem>
<listitem>
<para>
If the document has a table of contents, clicking on a table
of contents item will bring the document to to the page linked to that
item.
</para>
</listitem>
</itemizedlist>
<para>
Some documents have links. In this case you can click on them and the view will
change to the page it links to. If the link is to a web page the default &kde;
browser will be invoked.
</para>
<para>
Additionally, you may use the following functionality to quickly move to specific places
in the document:
</para>
<itemizedlist>
<listitem>
<para>
You can go to the first page of the document using
<keycombo action="simul">&Ctrl;<keycap>Home</keycap></keycombo> or
using
<menuchoice>
<guimenu>Go</guimenu>
<guimenuitem>First Page</guimenuitem>
</menuchoice>.
</para>
</listitem>
<listitem>
<para>
You can go to the last page of the document using
<keycombo action="simul">&Ctrl;<keycap>End</keycap></keycombo> or
using
<menuchoice>
<guimenu>Go</guimenu>
<guimenuitem>Last Page</guimenuitem>
</menuchoice>.
</para>
</listitem>
<listitem>
<para>
You can go to the next page of the document using
<keycap>Space</keycap>, <keycap>Page Down</keycap>, the <guibutton>Next Page</guibutton> Toolbar
button or using
<menuchoice>
<guimenu>Go</guimenu>
<guimenuitem>Next Page</guimenuitem>
</menuchoice>.
</para>
</listitem>
<listitem>
<para>
You can go to the previous page of the document using
<keycap>Backspace</keycap>, <keycap>Page Up</keycap>, the <guibutton>Previous Page</guibutton> Toolbar
button or using
<menuchoice>
<guimenu>Go</guimenu>
<guimenuitem>Previous Page</guimenuitem>
</menuchoice>.
</para>
</listitem>
</itemizedlist>
</sect1>
<sect1 id="presentationMode">
<title>Presentation Mode</title>
<para>
The Presentation mode represents another way to view documents in &okular;. It can be
enabled in
<menuchoice><guimenu>View</guimenu><guimenuitem>Presentation</guimenuitem></menuchoice>.
It shows the document on a page per page basis. The pages are shown with
zoom to page, that means all the page is visible.
</para>
<note>
<para>
&PDF; documents can even specify that they are always opened in presentation mode.
</para>
</note>
<para>
When in presentation mode, you have an helper bar located on the top of the screen. Just move
the mouse cursor to the top of the screen to make it appear.
</para>
<para>
To navigate between
pages you may use the &LMB; (next page) and the &RMB; (previous page), the mouse
wheel, the arrow icons or the line edit in the top bar,
or the keys specified in the <link linkend="navigating">Navigating</link>
section.
</para>
<para>
You can exit presentation mode at any time by pressing the <keycap>ESC</keycap> key or clicking
the <guiicon>Quit</guiicon> icon in the top bar.
</para>
<para>
Presentation mode has some configuration options, you can find their
description at <link linkend="configpresentation">Configuring &okular;</link>.
</para>
</sect1>
</chapter>
<chapter id="advanced">
<title>&okular; Advanced Features</title>
<sect1 id="embedded-files">
<title>Embedded Files</title>
<para>
If the current document has some files embedded in it, when you open it a yellow bar
will appear above the page view to notify you about the embedded files.
</para>
<screenshot>

<para>
In this case, you can either click on the link in the text of the bar or choose
<menuchoice><guimenu>File</guimenu><guimenuitem>Embedded Files</guimenuitem></menuchoice>
to open the embedded files dialog. The dialog allows you to view the embedded files and
to extract them.
</para>
</sect1>
<sect1 id="annotations">
<title>Annotations</title>
<para>
&okular; allows you to review and annotate your documents.
</para>
<sect2 id="annotations-add">
<title>Adding annotations</title>
<para>
To add some annotations to the document, you have to activate the annotating toolbar.
This is done by either slecting
<menuchoice><guimenu>Tools</guimenu><guimenuitem>Review</guimenuitem></menuchoice> or
pressing <keycap>F6</keycap>. Once you have the annotating toolbar, just press one of
its buttons to start constructing that anotation.
</para>
<para>
You can stop the construction any time by pressing again on the button of the
annotation you are constructing.
</para>
</sect2>
<sect2 id="annotations-remove">
<title>Removing annotations</title>
<para>
To remove an annotation, just click on it with the &RMB;, and select
<guimenuiem>Remove</guimenuitem>.
</para>
<para>
When removing the annotation, its window will be closed if open.
</para>
<note>
<para>
This option could not be enabled because the document does not allow removing
annotations.
</para>
</note>
</sect2>
<sect2 id="annotations-edit">
<title>Editing annotations</title>
<para>
To edit an annotation, click on it with the &RMB; and select
<guimenuiem>Properties...</guimenuitem>. A dialog will appear with the general

<para>
Depending on the document permissions (typically &PDF; documents), some options can
be disabled.
