    browser: Swap Left and Right arrow keys for RTL languages
    
    For a right-to-left language, we internally just swap the meaning of
    the right and left arrow keys. This means that the left key will dig
    deeper into a subcatalog and the right arrow will go back up or erase,
    consistent if everything else is RTL.
