LaunchBar is an application launcher for macOS. It provides access to user's applications and files, by entering short abbreviations of the searched item's name. It uses an adaptive algorithm that 'learns' a user's preferred abbreviations for a particular application. For example, after training, Adobe Photoshop may be launched by simply typing 'pho' and Time Machine can be opened by typing 'tm' even though that sequence of characters does not appear anywhere in the name of the application.
