Microsoft has released Skype 6.7, which completely overhauls the telephony app’s search feature. Now you can enter a term into the toolbar’s search field, and it will bring up a list of relevant conversations, as well as enabling you to explore your entire conversation history. A number of issues have also been resolved, including Skype hanging when closing the application during a call, being unable to hang up a call with the keyboard shortcut, and duplicate messages to Facebook contacts. There is an existing known issue with Mac OS X 10.7 Lion where the app sometimes crashes when clicking on profile pictures or file transfer icons. If Skype’s automatic update feature hasn’t yet gotten you the new version, choose Skype > Check for Updates, or download a copy from Skype’s Web site. (Free, 40.6 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.
