Modify the hotkey of Chinese-English language switching in Windows 10

目录

1. Modify the hotkey of Chinese-English language switching in Windows 10

The problem is very annoying because the hotkey ctrl+space has conflicted with others in emacs or other program. My thought is changing it to another combination ctrl+F1.

1. Open regedit
2. Navigate to HKEY_USER.DEFAULT\Input Method\Hot Keys\00000010\
3. Modify the Key Modifiers and Virtual Key.

4. Only disable the hotkey is change the first two digits of the two keys in 00.

   Key Modifiers: 00 c0 00 00.
   Virtual Key: 00 00 00 00
   

5. For Key modifiers, the rules of the number are like:

   __00__ c0 00 00 : The underlining two digits indicate one of modifier keys.
   
   CTRL: 02
   ALT: 01
   SHIFT: 04
   Disable: 00
   
   00 __c0__ 00 00 : The underlining two digits indicate the left or right position on the keybord.
   
   Left: 80
   Right: 40
   Left or Right: 8+4=12=c0
   

6. For virtual key, the rules are like:

   __00__ 00 00 00 : The hex of ascii of a virtual key.
   

   Please see the reference: https://docs.microsoft.com/en-us/windows/desktop/inputdev/virtual-key-codes

   So if we want F1, the hex code is 70:

   __70__ 00 00 00 : The hex of ascii of F1.
   

7. Restart your computer.

For my case, I just need to modify virtual key to 70 00 00 00
