MacOS下Home和End 以前使用keyfixer的一个app， 但是随着系统更新后，app就用不了。

cd ~/Library
mkdir KeyBindings
cd KeyBindings
vi DefaultKeyBinding.dict

写入以下内容

{
    /* 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:"; 


     /* Shift + Ctrl + Home Button */
    "$^\UF729" = "moveToBeginningOfDocumentAndModifySelection:";
    /* Shift + Ctrl + End Button*/
    "$^\UF72B" = "moveToEndOfDocumentAndModifySelection:"; 
}

然后就可以使用的了
