Several examples of software have been described as ''modal'' or using interface modes:
* [[Text editor]]s – typically are in insert mode by default but can be toggled in and out of [[overtype]] mode by pressing the [[Insert key]].
* [[Bravo (editor)]] – the first [[WYSIWYG]] modal editor made for [[Xerox Alto]] computers at [[Xerox PARC]] by [[Butler Lampson]] and [[Charles Simonyi]]
* [[vi]] – has one mode for inserting text, and a separate mode for entering commands. There is also an "[[Ex (text editor)|ex]]" mode for issuing more complex commands (e.g. search and replace). Under normal circumstances, the editor automatically returns to the previous mode after a command has been issued; however, it is possible to permanently move into this mode using ''Shift-Q''.
** Derivatives, such as [[Vim (text editor)|Vim]] and [[Neovim]]
* [[Emacs]] – has the concept of "prefix keys", which trigger a modal state by pressing the control key plus a letter key. Emacs then waits for additional keypresses that complete a [[keybinding]]. This differs from ''vi'' in that the mode always ends as soon as the command is called (when the sequence of key presses that activates it is completed). Emacs also has many "major and minor" modes that change the available commands, and may be automatically invoked based on file type to more easily edit files of that type. Emacs modes are not restricted to editing text files; modes exist for [[file browser|file browsing]], [[web browsing]], [[IRC]] and [[email]] and their interaction patterns are equivalent to [[application software]] within the Emacs environment. Modes are written in [[Emacs Lisp]], and all modes may not be included with all versions.
* [[Cisco IOS]] – certain commands are executed in a "command mode".
