Thank the Yumbo Lord

Windows Registry Editor Version5.00[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Keyboard Layout]"Scancode Map"=hex:xx,xx,xx,xx,xx,xx,xx,xx,Geneva,xx,xx,xx, -,xx, 1D,xx, 1D,xx, -,xx,xx,xx,xx,xx

Copy the above code on the Notepad. Files that are then saved in the. reg format.

Click on Execute, select Yes.

Then the reboot is done.

The following is a reference to the original text.

Key interpretation

Focus on the above code in the long string of binary, for easy analysis, split into every 8-bit line, and add line number, the result is as follows:

"Scancode Map"=Hex:xx,xx,xx,xx,xx,xx,xx,xx,Geneva,xx,xx,xx, -,xx, 1D,xx, 1D,xx, -,xx,xx,xx,xx,xx

The first two lines and the last line are fixed, all 8 0.

Line 3rd, that is, how many keys have changed, this example is 3, how to calculate? Starting from line 4th, to the very last line (although strictly speaking, the last row is not counted), each row counts 1, 4, 5, 6 rows, just 3.

The 4th line, the front and back 4 digits, respectively represents a key. In this example, the keys of the xx are mapped to 1 D,xx. , xx represents the left Alt key, 1D, andxx represents the left CTRL key.

Line 5th, in the same vein, the next line is left Ctrl mapped to left alt.

Line 6th, has been said, the last line, fixed 8 a 0. If you need to add more mappings, you can add more than 4, 5 rows on top of this line. The final result, of course, is to combine rows into one line.

There is also a special value of--00 00, which means nothing, if you want to disable a key, just map to 00 00.
