Problem: I am looking to add auto-scrolling--the function of panning a window after pressing the middle-mouse button--to my environment and all user applications. The best solution I've found is enabling Evdev Wheel Emulation
in xinput
as detailed here. In VirtualBox (guest OS: Fedora 23 stable; host OS: Windows 7), I am unable to find that property.
Terminal: Here is all output for xinput --list-props id
. This is one device:

Alternatives: There are two problems with the xinput
approach. First, one has to hold the middle-mouse button down (there is no use-as-a-toggle option). Second, windows will line jump instead of scroll smoothly unless there is an application-specific option as in Firefox. If any alternative approaches exist, they would also be answers here.
Motivation: I have always found it more comfortable to use auto-scroll for long pages or hunting and pecking instead of many flicks. Less generally, my mouse wheel is not functioning properly—a documented fault with my model.
