# The &kpdf; Handbook

## Introduction

&kpdf; is a &kde; PDF (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.

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.

## Using &kpdf;

### Opening Files

To view a PDF file in &kpdf;, select File Open... , choose a PDF or PS file in the dialogue and click Open. Your file should now be displayed in the main window.

If you have already opened files in &kpdf; before, you can quickly access them by selecting them in the File Open Recent menu.

After having a file opened you probably want to read it and therefore navigate through it. Click Next to learn more about this.

### Navigating

This section describes how you can navigate through a document in &kpdf;.

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 Tools Browse 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 the default browser 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, the Next Page Toolbar button or using Go Next Page .

- You can go to the previous page of the document using Backspace, the Previous Page Toolbar button or using Go Previous Page .

### Presentation Mode

The Presentation mode represents another way to view PDF documents in &kpdf;. It can be enabled in View Presentation. 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.

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 cursor to the top of the screen, 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 appearing if you move the mouse cursor to the top of the screen.

Presentation mode has some configuration options, you can find their description at Configuring &kpdf;.
