Editing Quicksilver (software) (section)

===Extensibility===

====Triggers====
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 {{Key top|[[Function key|F7]]}} key, this hotkey would trigger that action regardless of what application the user is currently in.<ref name="manual">{{Cite web|url=https://qsapp.com/wiki/Quicksilver_User%27s_Guide|title=Quicksilver User's Guide - Quicksilver Wiki|website=qsapp.com}}</ref>

====Plug-ins====
Quicksilver has a built-in [[Plug-in (computing)|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 (Apple)|Mail]] without opening the application or manipulating images via text commands.<ref name="manual"/>

====Flexibility====
Because [[shell script]]s and [[AppleScript]]s can be stored in the catalog, any function which can be performed with a script can be tied to Quicksilver through either the command window or triggers. Because most Apple-native applications have extensive scripting libraries, many common tasks can easily be performed from Quicksilver. For instance, [[iTunes]] can be told to play or pause, increase or decrease the current track's rating, or skip to the previous or next track.<ref name="manual"/>

There are various visual interfaces for Quicksilver,<ref>{{Cite web|url=https://qsapp.com/wiki/Interfaces|title=Interfaces - Quicksilver Wiki|website=qsapp.com}}</ref> Constellation Menus supporting [[mouse gestures]], and a Notification Hub which supports [[Growl (software)|Growl]].
