This plugin adds the ability to search for and manipulate running applications (processes), application windows, and application menu items from Quicksilver.

Access for assistive devices must be enabled in 'Universal Access' pane of System Preferences to use this plugin.


Processes represent applications which are currently running on your Mac. Any application in Quicksilver's catalog can be used as a process if that app is running. The following actions are available for processes:

Windows can also have several actions performed on them (you can view a full list in the Actions preferences by selecting 'Application Windows' from the dropdown types list). Several of the actions also have alternate actions (which can be executed with ⌘↩), you can see these in the same place in the Actions preferences:

Note: The 'Close', 'Minimize' and 'Zoom' actions work with the comma trick, allowing you to manage multiple windows at once

Menu Items only have one action available: Press. This has the same effect as clicking the menu item. To better indicate where Menu Items have come from, their details will show the full Menu path. For example: "Edit ▸ Find ▸ Find…"
