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 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.

The arrows will appear when you hover your mouse over the scrollbar.

Thanks Anemeth, there are now have scroll bars in Chrome and native KDE applications. Now all that's needed is scroll bars in Firefox, LibreOffice, and Evolution.
