-  // InputMethodAuraLinux take all key down events and send a character event
-  // to the TextInputClient. This causes a mismatch in code that has to be

-  // trying to have one way of doing things, we need to standardize on and
-  // emulate Windows character events.
-  //
-  // This is equivalent to what we're doing in the current Linux port, but
-  // done once instead of done multiple times in different places.
