tooltip-mode is an interactive and byte-compiled function defined in tooltip.el.gz.

Signature

(tooltip-mode &optional ARG)

Documentation

Toggle Tooltip mode.

This is a minor mode. If called interactively, toggle the Tooltip 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 \=tooltip-mode)'.

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

When this global minor mode is enabled, Emacs displays help text (e.g. for buttons and menu items that you put the mouse on) in a pop-up window.

When Tooltip mode is disabled, Emacs displays help text in the echo area, instead of making a pop-up window.

Probably introduced at or before Emacs version 21.1.
