Back Button on Mele F10 Pro

    Hi,

    I bought a Mele F10 Pro because it was used and cheap. ;)

    On the Mele F10 Deluxe there is a back button to the top right of the central circle.

    On the Mele F10 Pro this is instead the right mouse button.

    Not having a back button is a pain in the arse.

    What I do not understand:

    if I simply use a wireless mouse, the right mouse button works as both, back and context menu depending on where you click.

    I already tried the Keymap Editor Addon, but I just don't get it. Assigning is somehow the other way round than the keymap file? It does not receive the mouse-right-click so it just doesn't do anything.

    I tried this, but it doesn't work. Do I have to set this for every page not "global" alone?

    Code
    <keymap>
<mouse>    
<global>      
<rightclick>Back</rightclick>
</global>
</mouse>
</keymap>

    thanks
