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

			<title>Opening Files</title>
			<para>
				To view a PDF file in &kpdf;, select <menuchoice><guimenu>File</guimenu><guimenuitem>Open...
				</guimenuitem></menuchoice>, choose a file in the dialogue and click <guibutton>Open</guibutton>.
				As long as you selected a valid PDF file, your file should know be displayed in the main window.
			</para>
			<para>
				If you have already opened files in &kpdf; 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. Click
				Next 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 &kpdf;.</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
				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>, 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>, 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 PDF documents in &kpdf;. 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>
				To navigate between
				pages you may use the &LMB; (next page) and the &RMB; (previous page), the mouse
				wheel, the arrow icons that appear as soon as you move the mouse to the top of the screen,
				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 appearing if you move the mouse to the top of the 
				screen.
			</para>
			<para>
				Presentation mode has some configuration options, you can find their
				description at <link linkend="configpresentation">Configuring &kpdf;</link>.
