KeyTweak allows you to remap any key on your keyboard to any other key, or even to disable keys altogether. It does this by leveraging Windows' built-in key-remapping ability, but without the need to manually edit the Registry.
KeyTweak also includes "Teach Mode" allowing you to map keys to other keys simply by pressing the desired keys when promted.
KeyTweak is a simple utility that allows users to redefine their keyboard input signals. The functionality is made possible by a registry value first documented in Windows 2000, but also present in Windows NT 4.0. and included in XP, Vista and Windows 7.
How Does It Work? Simply put, KeyTweak is just a front-end interface for editing a particular registry key. Microsoft did the low-level heavy lifting by creating this registry key. KeyTweak makes the editing of it a little less geeky.
Your keyboard communicates with your computer typically through a PS/2 port or a USB port. The data sent by your keyboard is referred to as Scan Codes. When you press a key, the “make” scan code for that key is received by your computer’s i8042 controller chip. When you release a key, the “break” scan code is sent.
Prior to Windows 2000, device drivers had to be written to modify scan codes. Happily, Microsoft incorporated this feature into their operating system, thereby allowing fools like you and me to hack our registry and change the values to anything we see fit. The only downside is that the system has to be rebooted to take affect.
The registry key to which I’m referring is
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout and the binary value in that key is titled “Scancode Map”. If you forget this, don’t worry, just click the Show Me The Raw Map button to see what I’m talking about. Now, I don’t recommend registry hacking to anyone – that’s why I wrote this utility. If you don’t know what I’ve been talking about in this section, it’s probably better left forgotten.
