REGEDIT4 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout] "Scancode Map"=hex:00,00,00,00,00,00,00,00,02,00,00,00,1d,00,3a,00,00,00,00,00
To swap CapsLock and the left Control key, use:
REGEDIT4 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout] "Scancode Map"=hex:00,00,00,00,00,00,00,00,03,00,00,00,1d,00,3a,00,3a,00,1d,00,00,00,00,00
Save these as files with a .reg extension, and double-click on them in Explorer, or “run” them from a command prompt to have them update your registry (you may need to reboot).
It's a binary value that lets you map keystrokes in the low-level keyboard drivers in NT. As a result you don't have to worry about applications bypassing mappings that you've done at a higher level (i.e., it just works). Here's the format of the value: DWORD: 0x00000000 header DWORD: 0x00000000 header DWORD: length (in DWORDs) of remaining data, including terminating DWORD DWORD: mapping 1 ... DWORD: mapping n DWORD: 0x00000000 terminating null DWORD Each mapping DWORD has two parts: the input scancode, and an output scancode. To map scancode 0x1d (left control) to scancode 0x3a (caps lock), you want a value of 0x003a001d. Note that this does not swap the keys. Using just this mapping value, both the left control and the caps lock key will behave as caps-lock. To swap, you also need to map 0x3a to 0x1d, using 0x001d003a. This registry value is system wide, and can't be made user-specific. It also only takes affect on reboot.
