Here and the insertText below probably also need to convert to dispatchKeyEvent?
Or maybe this is intentional?

Was leaving it for a followup CL, but trivial enough to change.  Converted to
use keyTyped.

           repeatKey.key = this.lastPressedKey;
           repeatKey.timer = setTimeout(function() {
             repeatKey.timer = undefined;
             repeatKey.interval = setInterval(function() {
                insertText(detail.char);
             }, REPEAT_INTERVAL_MSEC);
           }, Math.max(0, REPEAT_DELAY_MSEC - REPEAT_INTERVAL_MSEC));
         }
       },

Does this break multiple character keys like ".com"? Or maybe I understand
wrong?

Good catch.  Fixed.
