nil

Documentation

Non-nil if Horizontal-Scroll-Bar mode is enabled.

See the horizontal-scroll-bar-mode(var)/horizontal-scroll-bar-mode(fun) command for a description of this minor mode. Setting this variable directly does not take effect; either customize it (see the info node (emacs)Easy Customization) or call the function horizontal-scroll-bar-mode(var)/horizontal-scroll-bar-mode(fun).

Probably introduced at or before Emacs version 25.1.
