@vindex scroll-bar-mode
To control the use of vertical scroll bars at startup, customize the
-variable @code{scroll-bar-mode}. Its value should be either
-@code{right} (put scroll bars on the right side of windows), @code{left}
-(put them on the left), or @code{nil} (disable vertical scroll bars).
-By default, Emacs puts scroll bars on the right if it was compiled with
-GTK+ support on the X Window System, and on MS-Windows or macOS; Emacs
-puts scroll bars on the left if compiled on the X Window System without
-GTK+ support (following the old convention for X applications).
