Peter Lewis of Stairways Software has released Keyboard Maestro 6.4.1, updating the essential automation utility with a number of bug fixes — there are no feature changes. The update fixes potential crashes when undoing Execute AppleScript actions, creating custom icons, and processing text tokens; prevents time triggers from executing twice due to timer drift; addresses a bug that could partially cancel actions that followed an Exit From Loop; and more.

Option-Click AirPort Menu for Network Details
If you hold down the Option key while clicking the AirPort menu in Mac OS X 10.5 Leopard, you'll see not just the names of nearby Wi-Fi networks, but additional details about the selected network. Details include the MAC address of the network, the channel used by the base station, the signal strength (a negative number; the closer to zero it is, the stronger the signal), and the transmit rate in megabits per second showing actual network throughput. If you hover the cursor over the name of a network to which you're not connected, a little yellow pop-up shows the signal strength and type of encryption.
