MacBook Home and End button not work

M1 MacBook 不再支援external keyboard 的home 同end 鍵，但可以用以下方法自己改返

1. 開啟 terminal
2. 輸入以下command
   mkdir -p ~/Library/KeyBindings
3. 用vim 開個新file
   vim ~/Library/KeyBindings/DefaultKeyBinding.dict
4. paste 返下面的setting 入去
   

{
/* Remap Home / End keys */
/* Home Button*/
"\UF729" = "moveToBeginningOfLine:"; 
/* End Button */
"\UF72B" = "moveToEndOfLine:"; 
/* Shift + Home Button */
"$\UF729" = "moveToBeginningOfLineAndModifySelection:"; 
/* Shift + End Button */
"$\UF72B" = "moveToEndOfLineAndModifySelection:"; 
/* Ctrl + Home Button */
"^\UF729" = "moveToBeginningOfDocument:"; 
/* Ctrl + End Button */
"^\UF72B" = "moveToEndOfDocument:"; 
 /* Shift + Ctrl + Home Button */
"$^\UF729" = "moveToBeginningOfDocumentAndModifySelection:";
/* Shift + Ctrl + End Button*/
"$^\UF72B" = "moveToEndOfDocumentAndModifySelection:"; 
}

最後記得 save and exit 就完，再reboot 一次就可以了
