Key Binding Home/End, Shift+Home/End on MacOS

TL;DR create ~/Library/KeyBindings/DefaultKeyBinding.dict containing:

  {
        /* Remap Home / End to be correct :-) */
        "\UF729"  = "moveToBeginningOfLine:";                   /* Home         */
        "\UF72B"  = "moveToEndOfLine:";                         /* End          */
        "$\UF729" = "moveToBeginningOfLineAndModifySelection:"; /* Shift + Home */
        "$\UF72B" = "moveToEndOfLineAndModifySelection:";       /* Shift + End  */
  }
