hmm unfortunately, the above does not work. I was able to get basic clicking working like this:

    cat .xbindkeysrc
    "xdotool click 1"
      Alt_R
    "xdotool click 3"
      Menu

    xset -r 108
    xset -r 135
    pkill xbindkeys && xbindkeys

but I wish dragging a mouse click would also work.
