KDE client-side accessibility library
Required to enable keyboard focus tracking

commit 035090bca3a3065800c6d9ff1862167170a0e939
Author: Sebastian Sauer mail@dipe.org
Date:   Tue Jul 20 20:33:23 2010 +0000
    Add a new 'Follow Focus' mode to KMag that uses the just new kaccessible QAccessibleBridgePlugin for providing keyboard cursor focus tracking.
    svn path=/trunk/KDE/kdeaccessibility/kmag/; revision=1152354
commit 2278a10a069ed436d0167ae3ef099b020e35f663
Author: Amandeep Singh aman.dedman@gmail.com
Date:   Wed Sep 26 02:46:22 2012 +0530
    Allowing KMag to follow both mouse + kbd-focus together
       -Made the followMouseMode + followFocusMode selectable together.
       -With just followMouseMode checked, Kmag follows mouse,
         and with followFocusMode checked, Kmag follows focus.
       -And when both are selected, it follows both the mouse,
         and the keyboard focus, whichever is relevant.

<para>
&kmagnifier; is a screen magnifier. You can use
&kmagnifier; to magnify a part of the screen just as you would use a lens to magnify
a newspaper fine-print or a photograph. This application is useful for a
variety of people: from researchers to artists to web-designers to people with
low vision. This document will try to be a complete reference manual for using
&kmagnifier;.

<title>Introduction</title>

<para>
&kmagnifier; is a screen magnifier by the KDE community. It can be used
to magnify a part of the screen. This application can be useful to various people:
People with low vision can use this application to magnify a part of the screen which they
are unable to view clearly,
artists can use this application to zoom into the graphics they produce and verify it
at the pixel level,
image-processing researchers can use this application to zoom into images and study them closely.
Other than these, &kmagnifier; can be used for various other purposes &eg; is possible to use the
application for grabbing a portion of the screen and saving it to the disk (with an option of
zooming the screen captured).
</para>
<para>
&kmagnifier; is a very powerful application with new features being added all the time. It is optimized
for use on low processing power machines.

<para>
After running &kmagnifier; you will get a window similar to the one show above. The main window of
&kmagnifier; shows the magnified (or zoomed) contents.
We refer to this window as the <quote>zoom window</quote>. The zoomed image shown inside the zoom window is
captured from a part of the screen. The part of the screen which is magnified is referred to
as the <quote>selection window</quote>.
</para>
<para>
By default, &kmagnifier; magnifies the region around the mouse cursor into the zoom window (think of it as a moving lens).
Alternatively, you can ask &kmagnifier; to magnify an chosen area of the screen 
(<guilabel>Selection Window Mode</guilabel>) or the whole screen 
(<guilabel>Whole Screen Mode</guilabel>) into the zoom window.
</para>
<para>
If you would prefer not to see the mouse cursor in the zoomed image, select
<guilabel>Hide Mouse Cursor</guilabel>. Please note that &kmagnifier; cannot yet find out the current cursor shape.
Thus, it shows the default cursor.
</para>

<sect1 id="changing-selection-window">
<title>Changing the part of the screen to be magnified</title>
<para>When in <guilabel>Selection Window Mode</guilabel>, the zoom window and the selection window can be moved and resized
using the &LMB; like any window.
You can also change the position and size of the selection window using the arrow keys on the keyboard,
or by clicking into the zoom window:
</para>

<variablelist>
<varlistentry>
<term><keycap>Arrow keys</keycap>, &LMB; or &MMB;</term>
<listitem>
<para>By keeping the &LMB; or &MMB; pressed in the zoom window and moving the
mouse, you can move the selection window.
You can also use the arrow keys if the selection window has the focus.</para>
</listitem>
</varlistentry>
<varlistentry>
<term><keycombo>&Ctrl;<keycap>Arrow Keys</keycap></keycombo> or
<keycombo>&Ctrl;<mousebutton>&LMB;</mousebutton></keycombo></term>
<listitem>
<para>By using this combination, you can resize the selection
window. Keep in mind that the top-left corner of the selection window
is kept constant and the bottom-right corner is movable.</para>
</listitem>
</varlistentry>
</variablelist>

</sect1>

<sect1 id="kmag-features">
<title>More &kmagnifier; features</title>

<para>&kmagnifier; comes with lots of features. It is possible to print the zoomed
image directly to a printer, save the image to a file, copy the zoomed
image to the clipboard (which can be used later to paste in other applications),
rotate the magnification image and more.
