Modifying the mapping of keyboard keys through the registry

Scancode Map of the magical, the keys to change freely!

in the Windows xp/windows 2000 system, a new keyboard scanning code mapping method is provided, allowing you to freely set the layout of keyboard keys, which is the "Scancode map" in the registry we cleverly use "Scancode map" The ordinary keyboard can be transformed into a casual personalized keyboard.

in order to set it up correctly, it is necessary to understand the "Scancode map" (Scan code map) first.

"Scancode Map" is a binary key value in [HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Keyboard Layout] in the registry (default is not, need to create new), and has a fixed format.
Scancode Map Code General format is: "hex:00,00,00,00,00,00,00,00,|02|,00,00,00,| map after the scan code (XX xx), the original scan code (XX xx) |00,00,00,00".

the meaning is:

The first 8 (DWORD two, 0) are the version number and the head byte, and

the next "02" represents the number of mappings, with a minimum value of "02", which means that only one set is mapped (the Numeric values are the number of mappings plus "00,00,00,00" at the end as the end, so they are always larger than the actual number of mappings, to map multiple groups, just add the corresponding values, such as mapping 2 groups whose values should be "03" and 3 Groups "04".
Behind the code every 4 is a group: the first two is the map after the key scan code, the latter two are the original key scanning code. If you want to exchange two keys, one has two sets of mappings, the four values are in the form of: Key A, key B, key B, key a--It means: Key A becomes key B, key B becomes key A. The
ends with "00,00,00,00".

Note: When you enter in the registry, you need to swap the high and low bytes of the scan code.
In addition, if you want a key to fail, map its scan code to "00 00".

To restore the original layout of keyboard keys, simply locate the registry [HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Keyboard Layout] and delete the "Scancode Map "key value

Special Note:

1. Under the current version of Windows, the keyboard mapping is global, not for a user, if you modify the addition or deletion of a mapping, then regardless of the user's use, the keyboard has changed;
In addition, if a computer has multiple keyboards, these keyboards will have the same change.
2. The power SLEEP WAKE up three keys cannot be closed on XP. (not personally tested, the notebook does not have these three keys, if it is not true to buckle it------joking, on the desktop, these three keys through the BIOS settings should be able to disable the corresponding function)
3. The "Fn" key on the ThinkPad cannot be mapped because it cannot be identified by the OS, so it cannot be set using the above method. ThinkPad new version of the BIOS provides a function, so that the left side of the "Fn" key and the adjacent "Ctrl" Key for functional exchange, the sense of usefulness is not very large, the need for friends can go to try. (If this feature is not found in the bios of the notebook, the BIOS needs to be refreshed, the operation is simple, do not fear)

After you import or set or modify or delete registry keys, Restart your computer , and the change takes effect.

You can also double-click the import registry by saving the following text as "Scancode.reg". The key value can be found by checking the above mentioned Keys table query, find the Scan code you want to replace, the ##,# #替换掉就可以了.

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Keyboard Layout]
"Scancode Map" =hex:00,00,00,00,00,00,00,00,02,00,00,00,##,##,##,##,00,00,00,00

Once we understand the "Scancode Map", we can use the Add function key. For example, the win key scanning code is: "E0 5B", ESC for "00 01", the left Ctrl for "1D", more detailed scan code see the keyboard scan code.

Example:

For

Example: the aforementioned IBM ThinkPad keyboard, in order to the browser page before and after browsing the key is forbidden, can be set to:

"Scancode Map" =hex:00,00,00,00,00,00,00,00,03,00,00,00,00,00,6a,e0,00,00,69,e0,00,00,00,00

For example: said we want to change the F9,F10 key to the volume adjustment key, through the table, you can know:
F9, F10 scan codes are (00,43), (00,44),
The scanning codes for Volume up and Volume down are (e0,30), (e0,2e), respectively,
This allows the scancode to be set as follows: "Scancode Map" =hex:00,00,00,00,00,00,00,00,03,00,00,00,30,e0,43,00,2e,e0, 44,00,00,00,00,00
(Meaning: | Version number and header byte |   Two sets of mappings | First Group | Group II | End Terminated | ）

I am the "back" and "forward" two keys mapped to "Page Up" and "Page Down", the registry file is as follows:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Keyboard Layout]
"Scancode Map" =hex:00,00,00,00,00,00,00,00,03,00,00,00,49,e0,6a,e0,51,e0,69,e0,00,00,00,00

Note again: all changes to the registry must be restarted before the computer can take effect .

Scancode the Map registry key to implement keyboard key mapping.

Located in the registry:

Create a new binary value entry under HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Keyboard layout\: "Scancode Map"

This project enables the mapping of keyboard keys. The meaning of the map here can be understood as "replace", which can replace any key with another key.

[Project format]

In 16 notation, divided into five parts, each comma is a byte.

"Scancode Map" = 00,00,00,00,00,00,00,00, 02,00,00,00, 01, 00, 02, 00, 00,00,00,00

1. 8 bytes. This is the version information number. Just write as usual.
2. 4 bytes. This is the total number of mapping keys. According to the binary reading and writing rules, the low is left and the high is on the right. 02 00 00 00 The number is actually: 00 00 00 02. Starting with 02, a mapping key is 02, two is 03, sliding scale in turn, and 10 is 0 B.
3. 2 bytes. Indicates the "Scan code" of the key after the replacement. For example: The ESC key scan code is 01, so it represents 01 00. Then the left CTRL key scan code is 1D 00, and the right CTRL key is 1D E0.
4. 2 bytes. Indicates the "Scan code" of the original key. Format Ibid.
5. Ended with four of 00.

[Keyboard Scan Code]

In hexadecimal notation, divided into two parts, 0X followed by two digits is the scan code, the last two numbers are ASCII (can be ignored). such as the 0x011b ESC Scan Code is 01.

4. Replace the left Crtl key with the left ALT key

"Scancode Map" =00,00,00,00,00,00,00,00,02,00,00,00,38,00,1d,00,00,00,00,00
