    name="1.1.1. The Toolbar Installation File|outline"></a> 1.1.1&nbsp; The
    <i>Toolbar</i> Installation File</h3>
    <p class="western c7">Currently two installation files will be required for a
    "complete" installation of all Accessibar features. One installs the toolbar into the
    browser (<span class="c12">accessibar.xpi</span>) and the second installs
    Accessibar's text-to-speech related Java classes (<span
    class="c12">InstallAccessibarReader_0_0_9.jar</span>). If you are just interested in
    Accessibar's visual web page manipulation features alone, installing Accessibar's
    text-to-speech reader as described in Step 2 can be skipped altogether.</p>
    <p class="western c7">The XPI installation file (<span
    class="c12">accessibar.xpi</span>) contains all the toolbar related directories and
    files needed. First we will install the toolbar into the browser:</p>
        <p class="western c7">Press <span class="c13"><u><a
        for the latest Firefox version of the Accessibar toolbar. Once the browser
        detects this as an extension installation file, the following dialog will

    alt="Image of Installation Confirmation Dialog" src="images/Fig1.png"
    name="graphics1" /></p>
    <p class="c16">Figure 1: Installation Confirmation Dialog</p>
    <p class="western c7">Confirm installation by selecting <b>Install</b>, and the
    toolbar will install itself into the browser's extensions directory. Next,
    <i>restart</i> the browser and the toolbar should appear within the browser as

    <p class="western c19"><br />
    <p class="c20">Figure 2: Installed Toolbar in the Browser's User Interface</p>
    <p class="western c7">At this point all the <i>non</i>-text-to-speech features of the
    toolbar should be fully functional. In our next (and final) installation step we will
    set up Accessibar's Java reader related classes.</p>

    <p class="western c7">I have made available a JAR based installer which automatically

        <p class="western c7">F<strong><span class="c28">ull keyboard access</span> <span
        class="c28">is ensured.</span></strong> All of the toolbars functions have
        <i>accesskeys</i> and/or<i>hotkeys</i>. (Accesskeys and hotkeys are both
        explained in the following <span class="c13"><u><a
        href="#_Menu_Accessibility">Menu Accessibility</a></u></span> section.)</p>
        <p class="western c7">An <span class="c13"><u><a
        href="#_Options_Configuration">Options dialog</a></u></span> is implemented which
        allows configurations to be carried out on hotkey (keyboard shortcut) settings as

        <p class="western c7"><span class="c13"><u><a href="#_Reader_Settings">Reader

        loaded and turned on when starting up the browser.</p>

    Menu Accessibility</h1>
    <p class="western c7">Accessibar ensures its functionality can be fully accessed
    using the keyboard. This is done by implementing <i>accesskeys</i> as well as
    configurable <i>hotkeys</i> for Accessibar's various functions.</p>
    <p class="western c7">An <i>accesskey</i> is an underlined letter in the menu or
    dialog that indicates to the user a quick, keyboard method of simulating a click on
    that element. On Windows and UNIX operating systems, pressing the underlined letter
    together with the <i>ALT</i> key will simulate a click. So if I wished to "click" on
    (open) Accessibar's <i>Accessibility Toolbar</i> menu button using the keyboard
    (where the A is underlined) I would press <i>ALT+A</i> which would then open the drop
    down menu.</p>
    <p class="western c7">A <i>hotkey</i> is defined at Mozilla's accessibility
    site<sup><a id="sdfootnote3anc" class="sdfootnoteanc" name="sdfootnote3anc"
    href="#sdfootnote3sym"><sup><span style="font-size: 12px">3</span></sup></a></sup> as "a key with a binding<sup><a
    id="sdfootnote4anc" class="sdfootnoteanc" name="sdfootnote4anc"
    href="#sdfootnote4sym"><sup><span style="font-size: 12px">4</span></sup></a></sup> that crosses widget boundaries, and can
    act globally in the current window". Basically these are key combinations that allow
    users to access frequently-performed actions quickly by using the keyboard to
    <i>bypass</i> the menu when carrying out commands. Since the hotkey bypasses the menu
    and is not dependant on an underlined letter in the command wished to carry out, I
    have created an <span class="c13"><u><a href="#_Options_Configuration">Options
    dialog</a></u></span> which allows hotkeys to be changed to suit the user's needs. In
    order to help avoid hotkeys conflicting with other hotkeys that may already be in
    place for the browser, all of Accessibar's configurable hotkeys are keys pressed in
    combination with Ctrl+Shift. Configuring hotkeys is described in the following
    <i>Running and Usage</i> section.<br />
    <br />

    <p class="western c7">Once the toolbar has been successfully installed it will appear
    in the browser's toolbox as displayed above in Figure 2. In this section I will

    name="4.1.Toolbars+Main+Menu"></a> 4.1&nbsp; Toolbar's Main Menu</h2>
    <p class="western c7">Accessibar's main menu can be found by pressing the
    <i>Accessibility Toolbar</i> menu button as shown in the following figure:</p>

    <p class="western c7">To the left of the dialog window a list of the available option
    categories appear. Currently users can configure hotkey (keyboard shortcut) settings
    as well as reader settings. The hotkey (keyboard shortcut) settings options page will
    be displayed on the right part of the options dialog window when the window is first
    loaded. The reader settings page can be navigated to by selecting <i>Reader</i> on
    the Category list.</p>

    <p class="western c7">All of Accessibar's main functionality features can be
    configured to being evoked using hotkeys of the user's choice. The hotkey preferences
    are stored in the user's home directory and therefore will be individual to all users
    that use the application on the same computer. All changes made to hotkey settings
    will take effect only after the browser is restarted.</p>

    Currently Accessibar provides two voices to choose from (Kevin16 and Kevin). Kevin16
    is a medium quality, 16 kHz voice and Kevin is a lesser quality 8 kHz voice. In
    addition to voice selection users can also control the voice's volume, speaking rate
    (speed), pitch and range. A <i>Restore Defaults</i> button is also provided which

    id="jws-10" name="jws-10"></a> After selecting <i>Reader On</i>, Accessibar will load
    the Java Virtual Machine which is needed to carry out this functionality. Once the
    JVM is fully loaded and the Reader service is up and running, the Reader will read
    out text on the web page as well as the browser's user interface elements when the
    mouse pointer hovers over an element. Focus events will also be read out loud so that
    users navigating through focusable elements (such as links) will also be able to hear
    these elements read out loud while tabbing though them using the keyboard.<br />
