fDesc[0] = "KeyTweak is a simple utility that allows users to redefine their keyboard input<br /> signals. The functionality is made possible by a registry value first documented in<br /> Windows 2000, but also present in Windows NT 4.0. and included in XP, Vista and<br /> Windows 7. This section lists some of KeyTweak&rsquo;s features and reasons you may want<br /> to use KeyTweak.<br /> <br /> Simply put, KeyTweak is just a front-end interface for editing a particular registry<br /> key. Microsoft did the low-level heavy lifting by creating this registry key. KeyTweak<br /> makes the editing of it a little less geeky.<br /> <br /> Your keyboard communicates with your computer typically through a PS/2 port<br /> or a USB port. The data sent by your keyboard is referred to as Scan Codes. When you<br /> press a key, the &ldquo;make&rdquo; scan code for that key is received by your computer&rsquo;s i8042<br /> controller chip. When you release a key, the &ldquo;break&rdquo; scan code is sent. Prior to<br /> Windows 2000, device drivers had to be written to modify scan codes. Happily,<br /> Microsoft incorporated this feature into their operating system, thereby allowing fools<br /> like you and me to hack our registry and change the values to anything we see fit. The<br /> only downside is that the system has to be rebooted to take affect.<br /> <br /> The registry key to which I&rsquo;m referring is<br /> HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout and the<br /> binary value in that key is titled &ldquo;Scancode Map&rdquo;. If you forget this, don&rsquo;t worry, just<br /> click the Show Me The Raw Map button to see what I&rsquo;m talking about. Now, I don&rsquo;t<br /> recommend registry hacking to anyone &ndash; that&rsquo;s why I wrote this utility. If you don&rsquo;t<br /> know what I&rsquo;ve been talking about in this section, it&rsquo;s probably better left forgotten.";
