Quicksilver (logiciel)

Résumé
Quicksilver is a utility app for macOS. Originally developed as proprietary freeware by Nicholas Jitkoff of Blacktree, Inc., it is now an open-source project hosted on GitHub. Quicksilver is essentially a graphical shell for the macOS operating system, allowing users to use the keyboard to rapidly perform tasks such as launching other apps, manipulating , or sending e-mail. It is similar to the macOS applications LaunchBar and Alfred, but uses a different interaction paradigm. Because of its flexible interface and extensibility, Quicksilver has been called one of the top productivity applications on the Mac. Invoked with a keyboard shortcut, Quicksilver has three panes, into which the user can enter an object, an action, and an optional attribute—analogous to creating a sentence with a subject, verb, and object. Quicksilver is a background application that runs while the operating system is running, maintaining a "catalog" of files and objects on the user's computer. By applying incremental search as the user types, Quicksilver predicts the filename or action typed by the user and automatically selects the object. Quicksilver uses a priority system based on prior usage to "learn" the user's habits, ultimately requiring only a few letters for the most commonly selected objects. Quicksilver allows users to define "triggers," which perform a specific command (direct object/action/indirect object combination) whenever a customizable keyboard shortcut is pressed. For instance, if a command opening the Documents folder is bound to the F7 key, this hotkey would trigger that action regardless of what application the user is currently in. Quicksilver has a built-in plug-in architecture, allowing the user to choose and install plug-ins providing integration with a specific program, interface, or new feature. For example, plug-ins exist for sending email via Mail without opening the application or manipulating images via text commands.
