Hey all,
I find remapping keys to be quite easy once you do it. You need three things.
1) Regedit (Everyone has this)
2)http://www.microsoft.com/hwdev/tech/input/w2kscan-map.asp
3) http://www.microsoft.com/hwdev/tech/input/Scancode.asp#New (Download the first
link: Keyboard Scancode Specification)
From there it's just a matter of matching up values. Follow what #2 says and create
a binary key called Scancode Map in that registry directory. Then you'll need to
edit/modify the Scancode Map key and first add 16 zeros (0).
From there, you'll need to figure out how many mappings you're going to make. I
use two, switching LWinKey and RAlt for gaming purposes, and Changing RWinKey into
a Mute button. So I then have a zero, a 3 (this number is how many mappings I'll
make), and then six more zeros. The values are reversed, it looks like 03,000,000,
but it's really 3. Complain to MS.
It should now look like this:
00 00 00 00 00 00 00 00
03 00 00 00
Of course, if you're making multiple changes, add to the 3. Now here's where you
need to look up the exact codes that you want to swap or remove. First look them
up by downloading and opening #3. Scroll down until you see the huge list of codes.
FIND THE KEY YOU WANT YOUR ORIGINAL KEY TO TURN INTO FIRST. This means if you wanted
to remove CAPS LOCK, you'd need to first find the null key which is 4 zeros (00 00).
You then add the character you wish the key to output when you press it first, exactly
opposite as their chart shows in #2.
So it should now look like this:
00 00 00 00 00 00 00 00
03 00 00 00 00 00
Then, if you wanted to remove CAPS LOCK, look up the key. The value right next to
the text Caps Lock (or any key you wish) is what you need to pay attention to. It's
3A for Caps Lock. However, when you want to enter this into the Scancode Map key,
you need to change it around some. First, there are two zeros missing. It should
be 3A 00. And even that is incorrect when you finally enter it in. You need to
swap each byte around so it looks like 00 3A to enter it in. This goes for each
code you enter. What looks like the last value is actually the first when you type
it into the Scancode Key.
It should now look like this:
00 00 00 00 00 00 00 00
03 00 00 00 00 00 00 3A
There. Caps Lock is removed. *If you wanted to turn Caps Lock into LCtrl it would
look like this: 1D E0 00 3A. This is so even though LCtrl's value is E0 1D.* Again,
complain to MS.
Now, you set 3 as the amount of keys you'd like to change, so let's make that happen
where LCtrl is now Caps Lock and then make Insert disappear. This is simple, as
you already know how to make Caps Lock into LCtrl as above **. All you need to do
is switch the values. It would be 00 3A 1D E0. Then, to remove Insert, you find
Insert (E0 70) and add the null value and then reversed Insert value (00 00 70 E0).
This all comes together:
00 00 00 00 00 00 00 00
03 00 00 00 00 00 00 3A
00 3A 1D E0 00 00 70 E0
Finally! This yields three effects. Pressing Caps Lock no longer does -anything-.
Pressing LCtrl turns Caps Lock on and off. And Insert too has no effect. To finish
it up, add four more bytes of zeros (00 00 00 00) and exit and reboot.
Final:
00 00 00 00 00 00 00 00
03 00 00 00 00 00 00 3A
00 3A 1D E0 00 00 70 E0
00 00 00 00
This is just some of the changes. You can go alter every key there is. Make Space
your Enter, and so on. I hope this helps you guys. Very easy to do again after
you do it once.
This is my simple personal Scancode Map:
00 00 00 00 00 00 00 00
02 00 00 00 38 E0 5B E0
20 E0 5C E0 00 00 00 00
And that turns LWinKey into RAlt and RWinkey into Mute.
Enjoy!
