QuicKeys ElectroOops -- I completely forgot to mention in TidBITS-127 what CE Software included in the QuicKeys upgrade, and I can't expect everyone to remember TidBITS-123, which talked about what would be in the upgrade. My apologies! It's too late for the upgrade now, but still, sorry about that.
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.
