Raspberry Pi 2 + Amazon Fire TV Remote Help


I ve spare Amazon Fire TV remore. Paired without problem and all basic keys working I have problem only with context menu button. I was trying to use Keymap Editor but when it says press key that you want to assign if I press key with 3 lines it does nothing. I tried 4 different keyboard.xml files from kodi.tv page but nothing helps to assign context key. Is anyone have any luck with this remote on OSMC?
