A tooltip (translated: tool help) is a small pop-up window in application programs or websites that shows the user a descriptive text for an element of the graphical user interface.
The tooltip appears when the user moves the mouse pointer for a short time ("Mouse over") and disappears automatically as soon as the mouse pointer is moved. Usually a few words appear in smaller, but a larger element can also appear, which also contains buttons, links or images.
Tooltips can contain supplementary information about the associated element that is otherwise not visible; but they can also show the text that the object itself contains.

In HTML and XHTML, an image map is a list of coordinates relating to a specific image, created in order to hyperlink areas of the image to different destinations (as opposed to a normal image link, in which the entire area of the image links to a single destination). For example, a map of the world may have each country hyperlinked to further information about that country. The intention of an image map is to provide an easy way of linking various parts of an image without dividing the image into separate image files.
