In addition to several under-the-hood refinements to give it a more snappy feel, Global Delight’s Voila 3.6 offers improved performance and reliability when running in OS X 10.9 Mavericks. In particular, the screen capture utility no longer crashes while importing files under Mavericks, and it fixes issues with taking screen captures using an external display and the menu bar. Voila 3.6 also improves its Text tool, retools the video export functionality for Macs running 10.7 Lion and later, enlarges the knob markers in the Capture and Object tools, and adds a German localization. Normally priced at $29.99, Voila has been discounted to $19.99 through 31 October 2013, and there’s a further 25 percent discount for TidBITS members when purchased through Global Delight. ($29.99 new from Global Delight or the Mac App Store, free update, 20.7 MB, release notes)
Sleep (and Lock) Your Screen
When you are walking away from your computer, it's fairly common practice to start your screen saver and lock your screen. But did you know that there is a built-in keyboard shortcut in Mac OS X to sleep the screen?
Press Control-Shift-Eject and your monitor sleeps without engaging the screen saver.
