ubuntu - How to emulate mouse scroll in openbox?

I use laptop a lot and have no mouse.
I use trackpoint which substitutes the mouse very well except scrolling.
Is it possible to bind scrolling of windows to - for example - 'Ctrl + middle + mouse?

I was using Ubuntu recently and found out that such feature is there. I mean if middle button is pressed then mouse moving scrolls windows content.

Answer

After longer research it turned out that it's matter of Xorg (instead of openbox as i thought initially).

I found 2 solutions:

1. Get zip from link (it's compressed dir from ubuntu with the feature):

   
   

   http://speedy.sh/jfpqM/emulate-scroll.zip

   
   

   Create backup of Your system dir:

   
   

   $ sudo cp -r /usr/share/X11/xorg.conf.d/ /usr/share/X11/xorg.conf.d-bck
   

   
   

   Replace dir "/usr/share/X11/xorg.conf.d/" with the one from zip. That's it.




2. get the dedicated program for that.. more info at links:
