Stairways Software has released a significant update to the popular macro utility Keyboard Maestro. Version 4.0 overhauls the user interface, adds 64-bit support, and adds support for Growl notifications. Macros can now be executed when hot keys are pressed, held down, or released. Also, Command-Tab can now be used as a hot key, the program switcher can optionally hide all other programs when switching, and the clipboard switcher now offers both a search feature and display of images and rich text. Version 4.0 requires Mac OS X 10.5 or later. ($36 new, $18 upgrade, 7.6 MB)
How to Make an iPhone Screenshot
Want to take a screenshot of something on your iPhone or iPod touch? Press the Home button and Power button briefly at the same time, and an image of your screen will be saved to the Photos app (and will sync with iPhoto when you next connect). Don't hold the buttons too long or your device will either power down or reboot.
