The tooltip or infotip or a hint is a common graphical user interface element. It is used in conjunction with a cursor, usually a pointer. The user hovers the pointer over an item, without clicking it, and a tooltip may appear—a small "hover box" with information about the item being hovered over.[1][2] Tooltips do not usually appear on mobile operating systems, because there is no cursor (though tooltips may be displayed when using a mouse).
