Function: horizontal-scroll-bar-mode

horizontal-scroll-bar-mode is an interactive and byte-compiled function defined in scroll-bar.el.gz.

Signature

(horizontal-scroll-bar-mode &optional ARG)

Documentation

Toggle horizontal scroll bars on all frames (Horizontal Scroll Bar mode).

This command applies to all frames that exist and frames to be created in the future.

This is a global minor mode. If called interactively, toggle the Horizontal-Scroll-Bar mode mode. If the prefix argument is positive, enable the mode, and if it is zero or negative, disable the mode.

If called from Lisp, toggle the mode if ARG is toggle. Enable the mode if ARG is nil, omitted, or is a positive number. Disable the mode if ARG is a negative number.

To check whether the minor mode is enabled in the current buffer, evaluate (default-value \=horizontal-scroll-bar-mode)'.

The mode's hook is called both when the mode is enabled and when it is disabled.
