Variable: horizontal-scroll-bar

horizontal-scroll-bar is a buffer-local variable defined in buffer.c.

Documentation

Position of this buffer's horizontal scroll bar.

The value takes effect whenever you tell a window to display this buffer; for instance, with set-window-buffer or when display-buffer displays it.

A value of bottom means put the horizontal scroll bar at the bottom of the window; a value of nil means don't show any horizontal scroll bars. A value of t (the default) means do whatever the window's frame specifies.
