In computer software, a mode is distinct method of operation within a computer program, in which the same user input can produce different results depending of the state of the computer. Computer software (or simply software) refers to one or more computer programs held in the storage of a computer for some purpose. ...

Several popular examples of software employing modes:

• vi - has one mode for inserting text, and a separate mode for entering commands. Some people also call vi's ability to line-edit a "mode" (even though it is launched outside of vi's normal interface, by invoking "ex" from the operating system's command line interface.)
• Emacs - has many modes that can be evoked based on file type to more easily edit files of a certain type. Modes are written in Emacs's LISP, and all modes may not be included with all versions.
• CIOS (Cisco Internetworking Operating System) - in order to gain the privilege to execute certain commands, you must enter a certain mode that allows you to execute that command.
• Also, tool palettes in photo-editing and drawing applications are classical examples of a modal interface.
