			<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 dialog and click <guibutton>Open</guibutton>.
				Your file should now be displayed in the main window.
			</para>
			<important>
			  <para>
			    The new document will be opened in a new tab should the <guilabel>Open new files in tabs</guilabel> option on the <link linkend="configgeneral">General configuration page</link> is checked.
			  </para>
			</important>
			<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>&okular; is the default &kde; application for &PDF; and &PostScript; files, launched when you click with the
			 &LMB; on such a file type in the filemanager. If you want to open any file whose format is supported by &okular;
			 use <menuchoice><guimenu>Open with...</guimenu><guimenuitem>&okular;</guimenuitem> </menuchoice> from context
			 menu in the filemanager.
			</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
				<keysym>Up Arrow</keysym> and <keysym>Down Arrow</keysym> keys. You may also use
				the scrollbar, your mousewheel or the <keycap>Page Up</keycap> and <keycap>Page Down</keycap>
				keys.
			</para>
			<para>
			  You can also use <application>vim</application>-like navigation keys, namely <keycap>H</keycap> to move to the top of the previous page, <keycap>L</keycap> to move to the top of the next page, <keycap>J</keycap> to move one line down, and <keycap>K</keycap> to move one line up.
			</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>
			<note>
			  <para>
			    When viewing a document in the <link linkend="presentationMode">Presentation mode</link> use <keysym>Up Arrow</keysym> and <keysym>Down Arrow</keysym> keys to switch between pages or slides. The number and the position of the current slide will be shown in the overlay at the right upper corner of screen.
			  </para>
			</note>
			<para>If you want to read a document with several pages use the automatic scrolling feature of &okular;.
			Start automatic scrolling with <keycombo action="simul">&Shift;<keysym>Down Arrow</keysym></keycombo> or
			<keycombo action="simul">&Shift;<keysym>Up Arrow</keysym></keycombo>. Then use these keys to increase and
			decrease the scrolling speed. You can start or stop automatic scrolling temporarily by pressing the &Shift; key;
			pressing any other key deactivates this feature.
			</para>
			<para>Another way to navigate through a document with several pages is to use the mouse pointer. Drag the page up or down, continue to drag even while reaching the bottom or top of the screen and behold.
			Once you cross the border of a page, the mouse cursor appears on top or bottom of the screen again and you can just continue to drag.
			</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 the page linked to that
						item.
					</para>
				</listitem>
				<listitem>
					<para>
						If the document has layers, you can control the layers shown by checking or unchecking
						the items in the <guilabel>Layers</guilabel> list.
					</para>
				</listitem>
				<listitem>
					<para>
						If the document has bookmarks, enable the <guilabel>Bookmarks</guilabel> view
						and click them to go to the associated page.
						If bookmarks are not only shown for the current document, you can quickly
						switch to bookmarks in all recently opened files.
					</para>
				</listitem>
				<listitem>
					<para>
						If the document has annotations, enable the <guilabel>Reviews</guilabel> view
						and click the annotations or select them with the <keysym>Up Arrow</keysym> and <keysym>Down Arrow</keysym> keys and press <keycap>Return</keycap> to go to the associated page.
					</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 or some
				other document the default &kde; handler for that format will be invoked.
				For example, clicking on a link pointing to <quote>http://www.kde.org</quote>
				will open the web page in the default &kde;'s web browser.
			</para>
			<important>
			  <para>
			    The document internal links work only when <link linkend="menutools">Browse Tool</link> is used.
			  </para>
			</important>
			<para>
				Additionally, you may use the following functionality to quickly move to specific places
				in the document:
			</para>
			<itemizedlist>
				<listitem>

							<guimenuitem>Beginning of the document</guimenuitem>
						</menuchoice>.
					</para>
				</listitem>
				<listitem>
					<para>

							<guimenuitem>Previous Page</guimenuitem>
						</menuchoice> in the menubar.
					</para>
				</listitem>
				<listitem>
					<para>
						You can go back to the positions in the document where you came from in a chronological order.
						Consider &eg; reading the phrase <quote>As shown in [15], …</quote>, and you want
						to know quickly lookup reference [15]. So you click on it, and &okular; will jump to the list
						of references. Using <keycombo>&Alt;&Shift;<keysym>Left</keysym></keycombo> or
						<menuchoice>
							<guimenu>Go</guimenu>

						</menuchoice> in the menubar will bring you back to exactly the position where you came from.
					</para>
				</listitem>
				<listitem>
					<para>
						You can go forward in the document after the jumping back as described above using
						<keycombo>&Alt;&Shift;<keysym>Right</keysym></keycombo> or

		    <para>
		      Drawing lines in &okular; is implemented in two steps: generation of the clipping path and filling this clipping path. When the line in the original document is less than one pixel this two step implementation could cause problems. For those lines, the clipping path is filled with the filling color that depends on the thickness of the line part inside the clipping area. If the part of the line inside the clipping area gets very small the contrast between the shape and the background color can become too low for the line to be recognizable. The grids of such lines then looks very unpretty.

With this option &okular; adjusts clipping path and line position so that clipping path and line are on the same pixel boundary, &ie; &okular; enlarges the thin lines to one pixel on the output device. This mode is similar to the <guilabel>Enhance thin lines</guilabel> in <trademark class="registered">Adobe</trademark>
