Has anyone else been unable to remap the rewind and fastforward buttons in fullscreenvideo mode? I'm able to remap all button functions in the other modes (global, virtualkeyboard), but cannot seem to change the functions of the fastforward or rewind buttons. I already use left/right to seek +/- 30s, and up/down for seeking +/- 10 min. I don't need the rewind/ff buttons, so I want to remap them to control subtitles and audio languages. I've also tried the Keymap Editor add-on, which also doesn't solve this issue (and I want to avoid it anyhow, as it does not seem to allow for "longpress" assignments at this point in time, thus limiting my options). 

For those that might want to know and may be able to help, here is my keymap section for <fullscreenvideo>:

<FullscreenVideo>
    <keyboard>
      <menu>Info</menu>
      <menu mod="longpress">CodecInfo</menu>    
      <backspace>Stop</backspace>
      <backspace mod="longpress">PreviousMenu</backspace>
      <browser_back>Stop</browser_back>
      <browser_back mod="longpress">PreviousMenu</browser_back>
      <up>BigStepForward</up>
      <down>BigStepBack</down>
      <left>Seek(-10)</left>
      <right>Seek(10)</right>    
      <rewind>NextSubtitle</rewind>
      <rewind mod="longpress">ShowSubtitles</rewind>
      <fastforward>AudioNextLanguage</fastforward>
    </keyboard>
  </FullscreenVideo>

Everything else above works fine, it's just that the <rewind> and <fastforward> assignments won't work - those buttons continue to perform their original functions when video is playing. Anyone else having this problem and/or anyone know how to solve this?

Edit: I'm using the current 4K Firestick model FYI.

It might be getting overridden by the global keymap -

xml:
<keymap>

  <global>

    <remote>

      ...

      <forward>FastForward</forward>

      <reverse>Rewind</reverse>

      ...

    </remote>

  </global>

</keymap>
