You don't even need this menu if you name your files correctly. Follow a naming rule like 'Avatar.3D.SBS.Blu-Ray.mkv' or 'Avatar.3D.OU.Blu-Ray.mkv'. The 'Blu-Ray' word is optional, it will show 3D Blu-Ray case in Aeon Nox skin. When you play this movie, a 3D menu will appear in the videos OSD.

If you want to edit the keyboard.xml file then open the folder 'C:\Program Files\XBMC\system\keymaps' and copy the keyboard.xml file to 'C:\Users\YourUserName\AppData\Roaming\XBMC\userdata\keymaps'. This folder is usually hidden. Open the copied keyboard.xml file in notepad and add <f1>stereomode</f1> as shown

Code:

<keymap>
  <global>
    <keyboard>
      <p>Play</p>
      <q>playlist.clear</q>
      <f1>stereomode</f1>

Start xbmc and press 'F1' to view the 3d modes.
