I am unable to scroll a document using the TrackPoint of my usb keyboard (under linux).
It works if the cursor is right over the scrollbars though.
(I could not find any further information about this issue, only an old thread by sponge using ST 1.4)

I will gladly provide any information necessary to solve the issue and test possible solutions.

Thank you in advance!

Do any of the issues found here github.com/SublimeTextIssues/Co … +scrolling help?

Unfortunately they do not help.
I tested the keyboard in combination with OSX Yosemite and everything works out of the box.

Under Linux it works for everything but sublime text.
I will test another distro and report back if it is due to my setup.
