   // This is a short-term workaround for the limitation that we're using
   // the ChromeVox content script to process touch exploration events, but
   // ChromeVox needs a way to distinguish between a real mouse move and a
   // mouse move generated from touch exploration, so we have touch exploration
   // pretend that the command key was down (which becomes the "meta" key in
   // JavaScript). We can remove this hack when the ChromeVox content script
   // goes away and native accessibility code sends a touch exploration
   // event to the new ChromeVox background page via the automation api.
