&FDLNotice; 2006-10-16 0.5.81 &okular; is a &kde; universal document viewer based on &kpdf; code. KDE okular pdf ps tiff djvu dvi chm xps &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. To view any supported file in &okular;, select FileOpen... , choose a supported file in the dialogue and click Open. Your file should now be displayed in the main window. If you have already opened files in &okular; before, you can quickly access them by selecting them in the FileOpen Recent menu. After having a file opened you probably want to read it and therefore navigate through it. Go to the next section to learn more about this. This section describes how you can navigate through a document in &okular;. There are multiple ways of scrolling the viewing area. One is to use the Up Arrow and Down Arrow keys. You may also use the scrollbar, your mousewheel or the Page Up and Page Down keys. 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 ToolsBrowse Tool . The navigation panel on the left side of the screen enables two more ways of navigating through a document: If you click on a page thumbnail the viewing area will be brought to that page. 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. 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. Additionally, you may use the following functionality to quickly move to specific places in the document: You can go to the first page of the document using &Ctrl;Home or using Go First Page . You can go to the last page of the document using &Ctrl;End or using Go Last Page . You can go to the next page of the document using Space, Page Down, the Next Page Toolbar button or using Go Next Page . You can go to the previous page of the document using Backspace, Page Up, the Previous Page Toolbar button or using Go Previous Page . The Presentation mode represents another way to view documents in &okular;. It can be enabled in ViewPresentation. 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. &PDF; documents can even specify that they are always opened in presentation mode. 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. 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 Navigating section. You can exit presentation mode at any time by pressing the ESC key or clicking the Quit icon in the top bar. Presentation mode has some configuration options, you can find their description at Configuring &okular;. 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. The embedded files bar The embedded files bar In this case, you can either click on the link in the text of the bar or choose FileEmbedded Files to open the embedded files dialog. The dialog allows you to view the embedded files and to extract them. &okular; allows you to review and annotate your documents. To add some annotations to the document, you have to activate the annotating toolbar. This is done by either slecting ToolsReview or pressing F6. Once you have the annotating toolbar, just press one of its buttons to start constructing that annotation. The annotating toolbar can be docked in any side of the pageview: just drag it to move it to another place. You can stop the construction any time by pressing again on the button of the annotation you are constructing. To remove an annotation, just click on it with the &RMB;, and select Remove. When removing the annotation, its window will be closed if open. This option could not be enabled because the document does not allow removing annotations. To edit an annotation, click on it with the &RMB; and select Properties.... A dialog will appear with the general annotation settings (like color and opacity, author, &etc;) and the settings specific to that annotation type. Depending on the document permissions (typically with &PDF; documents), some options can be disabled. &Ctrl;O File Open... Open a supported file. If there is already an opened file it will be closed.

The possible options are: Single (only one page per row), Facing (two pages per row, in a book style) and Overview (the number of columns is the one specified in the &okular; settings).
