The tooltip, also known as infotip or hint, is a common graphical user interface (GUI) element in which, when hovering over a screen element or component, a text box displays information about that element, such as a description of a button's function, what an abbreviation stands for, or the exact absolute time stamp over a relative time ("… ago"). In common practice, the tooltip is displayed continuously as long as the user hovers over the element or the text box provided by the tool.^[1] It is sometimes possible for the mouse to hover within the text box provided to activate a nested tooltip, and this can continue to any depth, often with multiple text boxes overlapped.

On desktop, it is used in conjunction with a cursor, usually a pointer, whereby the tooltip appears when a user hovers the pointer over an item without clicking it.^[2][3]

On touch-screen devices, a tooltip is displayed upon long-pressing—i.e., tapping and holding—an element.^[1] Some smartphones have alternative input methods such as a stylus, which can show tooltips when hovering above the screen.

A common variant of tooltips, especially in older software, is displaying a description of the tool in a status bar.^{[citation needed]} Microsoft's tooltips feature found in its end-user documentation is named ScreenTips.^[4] Apple's tooltips feature found in its developer documentation is named help tags.^[5] The Classic Mac OS uses a tooltips feature, though in a slightly different way, known as balloon help.^[6] Some software and applications, such as GIMP, provide an option for users to turn off some or all tooltips. However, such options are left to the discretion of the developer, and are often not implemented.^{[citation needed]}
