+ <title>Introduction</title>
+ <para>
+ Welcome to the <emphasis role="bold">VirtualBox Accessibility Support</emphasis> documentation! This document is primarily
+ a reference to help people who are interested in our project accessibility support and will describe how to use VirtualBox
+ user interface step-by-step. Since whole the application navigation will be explained here, this document will also be
+ helpful for those who are not familiar with our product user interface and wish to learn more. It will be written in a bit
+ excessive manner so that many obvious things will be explained too precisely to make it easier to understand by ear for a
+ blind users. The document will be periodically updated with recent changes and test-cases allowing us to more strictly
+ follow the required guidelines and make our product fully accessible.
+ </para>
+ <para>
+ Our application is based on Qt5, a powerful cross-platform library which allows to visualize various user interface ideas
+ the most flexible and native way. This also means that the library we use is responsible for many navigation and
+ accessibility aspects (like fonts, size hints, colors, look&amp;feel patterns and many other things), but not for all of
+ them. Nativity as one of the main ideas of the Qt-based application sometimes brings additional complexity because there is
+ always at least one host which uses unique combination of fonts and colors which breaks accessibility support in an
+ unpredictable way.
+ </para>
+ <para>
+ Independently on platform we are supporting screen-reader applications which can communicate with Qt5 accessibility
+ interface which supports Microsoft Active Accessibility (MSAA), OS X Accessibility, and the Unix/X11 AT-SPI standard.
+ </para>
+ <para>
+ Our application user interface is able to be started in two modes:
+ <itemizedlist>
+ <listitem>
+ <para>
+ First of them is <emphasis role="bold">VirtualBox Manager</emphasis> user interface, the main application window
+ which allows to manage and configure virtual machines and their groups. Besides that, this window provides user with
+ access to various global and machine related tools allowing to administrate some of VirtualBox objects and their
+ settings.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ Second application mode is <emphasis role="bold">Virtual Machine</emphasis> user interface, which allows to control
+ virtual machine guest screens as separate application windows. Besides that, this interface allows to access some of
+ machine tools and adjust guest screens up to your needs, by changing their resolution and toggling full-screen,
+ seamless and scaled modes.
+ </para>
+ </listitem>
+ </itemizedlist>
+ But first of all we should start from the <emphasis role="bold">General Concept</emphasis> which is related to whole the
+ GUI and summarizes the navigation and accessibility aspects we are using for whole application.
+ </para>
+ </chapter>
+
+ <chapter>
+ <title>General concept</title>
+ <para>
+ This chapter describes the general navigation and accessibility concept. We should note that not every detail of this
+ concept is already implemented and not every widget in our project already follows that concept. There is still large work
+ to be done in that regard. But in the end whole the project should correspond to this concept.
+ </para>
+ <para>
+ In short, every application window of our project should be navigated using the following approaches:
+ <itemizedlist>

+ <listitem><para>Screen-reader Navigation</para></listitem>
