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)
Turn Off Filename Extension Warning
In Leopard, Apple fixed an annoying aspect of working with the Finder in Tiger. Previously, if you changed a file's extension, the Finder prompted for confirmation. But since no one has ever accidentally changed a filename extension, Apple thankfully added an option to turn that warning off in the Leopard Finder's preferences. Choose Finder > Preferences, and in the Advanced screen, deselect Show Warning Before Changing an Extension.
