<p class="calibre8">The Hotkey control has limited capabilities. For example, it does not support mouse/joystick hotkeys or the Windows key (LWin and RWin). One way to work around this is to provide one or more <a href="#Gui.htm__CheckBox" class="pcalibre3 pcalibre1 pcalibre calibre5 pcalibre2">checkboxes</a> as a means for the user to enable extra modifiers such as the Windows key.</p>

<p class="calibre8">To use a picture as a background for other controls, the picture should normally be added prior to those controls. However, if those controls are input-capable and the picture has a <a href="#Gui.htm__label" class="pcalibre3 pcalibre1 pcalibre calibre5 pcalibre2">g-label</a>, create the picture after the other controls and include +0x4000000 (which is WS_CLIPSIBLINGS) in the picture's <em class="calibre21">Options</em>. This trick also allows a picture to be the background behind a Tab control.</p>
