How can I set up my system so that windows have scroll bars with arrows. The mouse scroll wheel works OK for vertical scrolling, but not for horizontal. I now need to edit a spread sheet with 29 columns. Grabbing the line in the scroll bar is tedious and finicky. I'd like this for native KDE applications, Gnome applications running under KDE, Firefox, and Chrome.

System is Fedora-27 with all updates installed.
