+The `outsideClick` trigger will cause the tooltip to toggle on click, and hide when anything else is clicked.
+
 For any non-supported value, the trigger will be used to both show and hide the
 tooltip. Using the 'none' trigger will disable the internal trigger(s), one can
 then use the `tooltip-is-open` attribute exclusively to show and hide the tooltip.
