Where to find windows keyboard scancode registry information?

Question

I am in the process of remapping some keys on my Windows 7 keyboard.

I have done the following (in a .reg file):

[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 

I am interested in being able to remap other keys. However, I am having a heck of a time finding the specific scan codes to do this.

Is there a listing of these scan codes somewhere? I've spent a fair bit of time trying to find information and other than the caps/control I cannot seem to find them. I would like a listing of all scan codes - in a format which makes sense for remapping.

The specific keys I am interested in are:

• Menu button (wtf windows)
• windows key
• alt
• shift
• function
• insert
• pause

UPDATE: I found a more complete list of scan codes:

I found this guide to help others understand how to remap keys using registry: https://isenselabs.com/posts/keyboard-key-kills-and-remaps-for-windows-users

But you already know how to do that, and you just need to have a list of scancodes, so here goes:

   SC Key   SC Key   SC Key        SC Key        SC Key       SC Key

The keycode that you're going to use in registry consists of two parts for example: 4B E0 which is left arrow or 0F 00 which is Tab key, in the above list you will find the first part of the key code 4B for example, the second part usually is 00 or E0 I have no idea what the second part is and I couldn't find anything on it and I'm writing this out of my own findings, do some trial and error and you will find your key.

@fabianroling and anyone else who can't use third-party software: the Keyboard Scan Code Specification from Microsoft has the definitions for all the scan codes. It also says the following:

Under all Microsoft operating systems, all keyboards actually transmit Scan Code Set 2 values down the wire from the keyboard to the keyboard port. These values are translated to Scan Code Set 1 by the i8042 port chip. The rest of the operating system, and all applications that handle scan codes expect the values to be from Scan Code Set 1.

So, nothing Windows-specific, just standard Set 1 codes.

If you want to do it the easy way, you can simply use SharpKeys, KeyTweak or similar utilities.

If you're simply after scancodes, the same programs should be able to help:

Does this Microsoft link help you further?

[enderland]

@nixda I've seen that but it does not provide the actual scan codes to use (as best I can tell)

[Admin]

Mind that in my Windows 7 64 bit Pro, [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboar‌​d Layout] is empty, no Scancode key there.

[AuralArch]

BTW, FYI: on very few keyboards (other than Apple's) does the Fn/function key produce any scancode. Instead, when it is pressed in combination with certain other keys a certain, unique scancode is sent as if that other key was pressed alone instead of two keys. the pause key is the one key whose scancode can not be changed in the windows registry.

[Fabian Röling]

This answer doesn't actually help anyone who isn't allowed to install third party software on the current computer (like me). If I was allowed to use this program to find out scancodes, I might as well just use the program to remap keys.

I'm extremely confused as to the how and where to input the number pairs. How do you know? Or does it not matter? Which of the 00 do you replace?

[Shayan]

It's very simple, ESC::A this code will type a every time you hit the escape key, if you want to use the scan code from my list, do this: SC01::A

[Tom]

I dont think that works @shayan. It needs to be in a hex form with two characters. Your answer is incorrect. After some digging I figured it out through sharpkeys anyway, they had a perfect answer already.

That list doesn't contain all of the scan codes OP was asking for. It's missing the WIndows key, menu key, and possibly others.
