Usage in computer system menus
In computer menu functions or buttons, an ellipsis means that upon selection more options (sometimes in the form of a dialog box) will be displayed, where the user can or must make a choice. If the ellipsis is absent, the function is immediately executed upon selection. For example, the menu item "Save" indicates that the file will be overwritten without further input, whereas "Save as..." indicates that a dialog follows where the user can, for example, select another location, file name, or format. Ellipses are also used as a separate button (particularly considering the limited screen area of mobile apps) to represent partially or completely hidden options. This usage may alternatively be described as a "More button" (see also hamburger button signifying completely hidden options). In mobile, web, and general application design, the vertical ellipsis, ⋮, is sometimes used as an interface element, where it is sometimes called a kebab icon. The element typically indicates that a navigation menu can be accessed when the element is activated, and is a smaller version of the hamburger icon (≡) which is a stylized rendering of a menu. In mathematical notation
An ellipsis is also often used in mathematics to mean "and so forth".
As a device, the ten-ten-ten is intended to focus the reader on a character while allowing the character to not speak any dialogue. This conveys to the reader a focus of the narrative "camera" on the silent subject, implying an expectation of some motion or action. It is not unheard of to see inanimate objects "speaking" the ellipsis. In Chinese
In Chinese, the ellipsis is six dots (in two groups of three dots, occupying the same horizontal or vertical space as two characters) (i.e. ……). In Spanish
In Spanish, the ellipsis is commonly used as a substitute of et cetera at the end of unfinished lists. So it means "and so forth" or "and other things". Other use is the suspension of a part of a text, or a paragraph, or a phrase or a part of a word because it is obvious, or unnecessary, or implied. For instance, sometimes the ellipsis is used to avoid the complete use of expletives. When the ellipsis is placed alone into a parenthesis (...) or—less often—between brackets [...], which is what happens usually within a text transcription, it means the original text had more contents on the same position but are not useful to our target in the transcription. When the suppressed text is at the beginning or at the end of a text, the ellipsis does not need to be placed in a parenthesis. The number of dots is three and only three. In French
