When non-empty describes the text to use in a tooltip for the GUI tab
pages line. When empty Vim will use a default tooltip.
This option is otherwise just like 'guitablabel' above.
You can include a line break. Simplest method is to use :let:
:let &guitabtooltip = "line one\nline two"
(default empty)
only available when compiled with GUI enabled
