KeyTweak Use Broken Keyboard Without Repairing

KeyTweak is a smart tool that was created to offer users an easy way of modifying different functions of a keyboard. It proves to be a useful solution especially for laptop owners that have trouble with damaged keys on their keyboards. KeyTweak will edit a certain registry entry in order to change different values assigned to different keys from the keyboard. This is a safer manner of editing registry keys than manually hacking Windows registry.

All the necessary tools are available on the interface of KeyTweak. It displays a keyboard layout that you can use to select a specific key in order to change its function. For example, if the “Space” key is damaged and can no longer be used, you can assign its code to the Left Alt key. In a similar way, gamers can assign various functions to specific keys.

KeyTweak comes with its own limitations. For example, it cannot handle key combinations. It was designed to work with the “scan codes” of individual keys and it won’t recognize a certain code generated by the keyboard processor for a specific keyboard shortcut. Also, the program is not able to affect the functionality of the Fn key (a modifier key on many keyboards, most recently on laptops).

I strongly recommend this program to anyone who is dealing with various keyboard issues.

Publishers description

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. This section lists some of KeyTweak’s features and reasons you may want
to use KeyTweak.

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_MACHINESYSTEMCurrentControlSetControlKeyboard 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.
