    Update arrow keys for left and right based on current locale.
    Note: this method is used internally by built-in GWT widgets but could be renamed/refactored without notice.
    This method simplifies RTL handling in your code:
```
 int keyCode = KeyCodes.maybeSwapArrowKeysForRtl(event.getKeyCode(),
   LocaleInfo.getCurrentLocale().isRTL());
 switch (keyCode) {
   case KeyCodes.KEY_LEFT:
     ... // start of the line, no special RTL handling
     break;
   case KeyCodes.KEY_RIGHT:
     ... // end of the line, no special RTL handling
     break;
   ...
   }
 
```
