Documentation

If non-nil, text is shown by a tooltip in a graphic display.

If this option is nil, mouse-drag-and-drop-region(var)/mouse-drag-and-drop-region(fun) does not show tooltips. If this is t, it shows the entire text dragged in a tooltip. If this is an integer (as with the default value of
256), it will show up to that many characters of the dragged text
in a tooltip.

This variable was added, or its default value changed, in Emacs 26.1.

Probably introduced at or before Emacs version 26.1.
