Trackpoint scroll (Windows 10)?

Is there any way to enable scrolling via Trackpoint? Lenovo laptops have middle button for that, which can you can hold and move Trackpoint, and I am missing similar feature on my ZBook 14u (G5). Makes Trackpoint quite useless... Maybe remap right button for scroll?

 

A Lenovo laptop ser here.
I have disabled Lenovo's scroll feature due to it completely disabling middleclick.

I had a reasonably good result with AutoHotkey script, provided in this thread:
http://forum.notebookreview.com/threads/ultranav-middle-click-button-scroll.423415/page-3

I have also used AutoHotkey to bring back the numpad at JKLUIO keys, while holding left Alt key (Fn did not work).

I want, however, some guidance on how to make it work only on the trackpoint, but not external mouse, as I need my middle button in CAD programs.

 

That Autohotkey script looks cool, but does not seem to work at all on EliteBook (have compiled this http://forum.notebookreview.com/threads/ultranav-middle-click-button-scroll.423415/#post-5951581 script and run it). Probably those trackpoint buttons are not MButton Up, MButtonup?

 

Is there no setting in the mouse/touchpad control panel? It's where it is for my Dell (though obtusely hidden behind a picture of the touchstick).

 

Try this code:

I have modified it to disable the scroll function in one of my CAD programs, but to work everywhere else. You may want to remove lines 1,7,8 and first part of if() on line 9, if you want no exceptions.

Edit: Just noticed you don't have a middle button on your machine... You can do a left ctrl + right mouse by modifying the script slightly. Here are seme details on how to do that: https://www.autohotkey.com/docs/Hotkeys.htm
I believe something like this should work:
