For example, many programs have a "File" drop down menu at the top left of their screen. Clicking on the "File" text generates a new menu with additional options. It might seem surprising, but there is also a dropup, apart from the traditional dropdown.

In other words, a tooltip is a message which appears when a cursor is positioned over an icon, image, hyperlink, or other element in a graphical user interface.

Tooltips do not usually appear on mobile operating systems, because there is no cursor.
