<title>Introduction</title>
&kvkbd; is a simple virtual keyboard for &tde;.
<sbr/>It can be used with, or instead of, a physical keyboard or for devices with a touch screen but no keyboard.
<sbr/>It is also useful for displaying a keyboard mapping to identify what characters are defined.
</chapter>
<chapter id="using-kvkbd">
<title>Using &kvkbd;</title>
<sect1 id="kvkbd-interface">
<title>&kvkbd; interface</title>
When first launched, &kvkbd; will appear in the bottom-right corner of the screen.
<sbr/>It can be moved by clicking and dragging on any part of the background area.
<sbr/>Resize it by clicking and dragging on the stripes at the bottom right.
<sbr/><sbr/>The default style will be the system style which can be overridden whether launched from the command line or via the .desktop file with any &tde; or &TQt; style installed on the system.
<sbr/>Example: <command>kvkbd --style plastik</command>, as shown here.
<sbr/><sbr/>The <guiicon><inlinegraphic fileref="exit-btn.png"/></guiicon> button on the top right is used to hide the keyboard - to show it again, just click on the tray icon.
<sbr/><sbr/>
<emphasis role="bold">French keyboard:</emphasis>
<sbr/>The AD11 key, ringed, is a <link linkend='dead-keys'>dead key</link>.
<mediaobject><imageobject>
<imagedata fileref="kvkbd.png" format="PNG"/>
</imageobject></mediaobject>
<sbr/>
To use the numeric keypad, click the double arrow <guiicon><inlinegraphic fileref="num-pad-btn.png"/></guiicon> on the right.
<sbr/>The Num pad display can be toggled by clicking on the Num Lock key <keycap>&#x02116;</keycap>.
<mediaobject><imageobject>
<imagedata fileref="num-pad.png" format="PNG"/>
</imageobject></mediaobject>
<sbr/>
To display and select the shift characters:
<sbr/>&nbsp;&#x02022; Click either &Shift; key, which will 'lock', and the shift characters will be displayed.
<sbr/>&nbsp;&#x02022; Then click on the character to print it.
<sbr/><sbr/>
<emphasis role="bold">Spanish keyboard shift characters:</emphasis>
<mediaobject><imageobject>
<imagedata fileref="kvkbds.png" format="PNG"/>
</imageobject></mediaobject>
<sbr/>
3rd &amp; 4th level characters which are printed using &AltGr; &amp; &AltGr;+&Shift; as modifier keys, can be displayed and printed in a similar way.
<sbr/><sbr/>
There are therefore four sets of characters which can be displayed -
<sbr/>
<keycap>Lower</keycap>&ensp; &Shift;&ensp; &AltGr;&ensp; &AltGr;+&Shift;
<sbr/><sbr/>
For each of these, &Caps; will toggle the case of alpha characters where a lower/upper pair is defined in UnicodeData.txt &amp;&amp; &TQt; &amp;&amp; libX11.
</sect1>
<sect1 id="config-menu">
<title>The configuration menu</title>
The &kvkbd; configuration menu is accessible by clicking on the configuration button <guiicon><inlinegraphic fileref="config-btn.png"/></guiicon> or by right clicking on the tray icon.
<mediaobject><imageobject>
<imagedata fileref="config-menu.png" format="PNG" />
</imageobject></mediaobject>
Select "<emphasis role="bold">Font</emphasis>" to choose the font used to display the characters and text on the keys.
<sbr/>Allows selection of the style and size.
<sbr/><sbr/>Check "<emphasis role="bold">Auto Resize Font</emphasis>" for the font size to change as the keyboard is resized.
<sbr/><sbr/>Select "<emphasis role="bold">Background color</emphasis>" to choose a colour for the keyboard background.
<sbr/><sbr/>Select "<emphasis role="bold">Key color</emphasis>" to choose a colour for the keys/buttons.
<sbr/><sbr/>Check "<emphasis role="bold">Dock Widget</emphasis>" to display a small dock which can be placed anywhere on screen.
<sbr/>Click on the dock to hide or show the virtual keyboard.
<sbr/><sbr/>Check "<emphasis role="bold">Lock on screen</emphasis>" to fix the position and size of the keyboard on the screen.
</sect1>
<sect1 id="keys">
<title>Keys</title>
The &kvkbd; keyboard is based on the US layout with an extra key to the right of Left &Shift; for non-US keyboards - the extra key duplicates the '<emphasis role="bold">&lt;</emphasis>' and '<emphasis role="bold">></emphasis>' characters on the US keyboard.
<sbr/><sbr/>
For non-US keyboards, the key which is normally lower left of the &Enter; key is placed above the &Enter; key.
<sbr/><sbr/>
&AltGr; will enable selection of the character mapped to the lower right of any key, and &AltGr;&nbsp;&Shift; for any upper right character where they have been set up in the keyboard mapping file [<filename>&lt;path_to>/X11/xkb/symbols/</filename>].
<sbr/>
<emphasis role="bold">Note</emphasis> that there are two possible gotchas in displaying the &AltGr; characters:
<sbr/>
&nbsp; &#x02022; they tend to be less commonly used and might not have glyphs in the font being used,
<sbr/>
&nbsp; &#x02022; the keyboard mapping file needs to <emphasis role="bold">include&nbsp;"level3(ralt_switch)"</emphasis> for the variant being used.
<sbr/><sbr/>
The &Shift;, &Ctrl;, <keycap>Alt*</keycap> keys 'lock' when clicked to simulate holding down a key on a physical keyboard.
<sbr/>
Whether the <keycap>*Win</keycap> keys 'lock' will depend on the build time option chosen.
<sbr/><sbr/>
<sect2 id="dead-keys">
<title>Dead Keys</title>
Using &Shift; and/or &AltGr; which need press and hold on a physical keyboard will need click only for &kvkbd;.
<sbr/><sbr/>For example, using the AD11 key [ ˆ ] on the oss variant of the French keyboard:
<sbr/><sbr/><command>setxkbmap fr -variant oss</command>
<informaltable>
<tr>
<td>Character:</td><td></td>
<td>dead_circumflex</td><td>&nbsp;</td>

</informaltable>
<sbr/>
<emphasis>Note</emphasis> that &kvkbd; is compiled for keycodes defined by evdev&nbsp;&#x000bb;&nbsp;<filename>/etc/X11/xkb/keycodes/evdev</filename>.
<sbr/>&kvkbd; will have reduced functionality in systems using another keycode definitions file which can be checked by:
<literallayout> &#x02022; running <command>xev</command> in a konsole
&#x02022; pressing or clicking <keycap>Menu</keycap>
&#x02022; looking for <code><emphasis>keycode 135</emphasis></code> among the output
</literallayout>
</sect2>
<sect2 id="comb-keys">
<title>Combining Keys for diacritics</title>
A similar function to dead keys, but they follow the handwriting sequence of character+diacritic.
<sbr/><sbr/>For example, using the AE12 key [ ´ ] on the ru-recom variant of the German keyboard:

<sbr/><sbr/>If &kvkbd; has been built for the <keycap>Win</keycap> keys not to function as modifier keys, they can conveniently be used for frequently used characters which might otherwise be more cumbersome to generate.
<sbr/><sbr/>For example, the <emphasis role="bold">"</emphasis> and <emphasis role="bold">*</emphasis> characters on a gb keyboard are &Shift;+<keycap>2</keycap> and &Shift;+<keycap>8</keycap>, and they could be assigned to the Win keys:
<literallayout><command>&xmmp; -e 'keycode 133=quotedbl'</command>
<command>&xmmp; -e 'keycode 134=asterisk'</command>

Then <keycap>LWin</keycap> would print <emphasis role="bold">"</emphasis> and <keycap>RWin</keycap> would print <emphasis role="bold">*</emphasis>
