I have been able to remap the CapsLock key (3A) to the Left Shift key (2A) by adding the binary value HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout\Scancode Map to the registry with a value of:

00 00 00 00  00 00 00 00

02 00 00 00  2A 00 3A 00

00 00 00 00

How can I modify this value so that the key remaps to a multiple-key combination, for example Alt-Shift?

I thought Keyboard Layout could only be used to map one key to another one. Is there any restriction from using third party apps? AutoIt or AutoHotKey would be perfect for this – Martheen Cahya Paulo Aug 9 '11 at 5:00
Thanks. I can definitely do this with AutoHotKey, however I was hoping that I could do it in the registry so that I wouldn't have another process running. If this can't be done in the registry, then I guess that's my answer. – Paul Williams Aug 9 '11 at 5:23
AutoHotKey is my third party app of choice for this sort of thing. – Windos Aug 9 '11 at 5:26

there are two options shown here at AutoHotKey: Remapping via the Registry's "Scancode Map" , might be what you are looking for...

(1) Use a program like KeyTweak (freeware) to visually remap your keys. It will change the registry for you.

(2) Remap keys manually by creating a .reg file (plain text) and loading it into the registry. This is demonstrated at

While neither of these solutions do exactly what I was looking for, the information you gave me has helped lead me to the conclusion that what I want to do is probably not possible with the registry. It appears that AutoHotKey or something similar is my best bet. – Paul Williams Aug 11 '11 at 14:49
