The open-source keyboard launcher Quicksilver has been updated to version β69, a maintenance update with a plethora of fixes that also adds support for OS X 10.8 Mountain Lion. The release now enables Quicksilver’s “paste” action and internal shortcuts to work for all keyboard layouts, makes Automator actions universal, and fixes sporadic opening and closing of the Quick Look panel. It also allows the app’s preferences to be localized and adds French localization. (Free, 3.3 MB, release notes)
Two Shortcuts for App Exposé
If you want to see all the windows for a particular app via App Exposé, there are two hidden shortcuts. For either, start by pressing Command-Tab to bring up the app switcher. Then, while still holding down the Command key, press either the 1 key or the up arrow. That puts you into App Expose mode, with all of an app's windows showing, and recent documents in a row across the bottom of the screen. Let up on the Command key, and then you can press Tab to cycle through all the running apps.
