In Mac OS X 10.5, in the menu bar AirPort icon in the sleeves of their game - hold down the option, click on the icon, you'll see more about the variety of available information on AirPort networks. In the snow leopard, this feature has been expanded, not only for the airport menu, but for some others.

Here's what you'll see when you hold down the Option key and click on various menu bar icons:

AirPort: In addition to hardware (MAC) of wireless stations, the channel is using the address, signal strength (RSSI) data transfer rate of the last instruction (10.5 of all available), you can also see what your model of the network connection to use (for example, 802.11 n standard), security (WPA2 Personal, etc.), and a microcontroller called the index, which seems to 802.11n standard. (If you really put these things you always check this table microcontroller index value; explain that you will find there, but then, depending on you!).

Sound: If you have more than one voice input and / or output on a Mac using, you'll love this change. Rather than using terms such as SoundSrouce, third-party or open System Preferences application, select only click the sound icon. Rather than the usual volume slider, you will see the output and input devices available to the list; just select one from the list to use the output or input device. This is a great time to save.

Battery: When your battery icon Option key, you will see a normal, replace the soon to replace one now, or service the battery next to the word condition. Click this, as well as Apple's help page will open, explaining the meaning of each - if they are not fully self-explanatory. Apple has also been supporting documents to explain more about the state of the battery. While the cynic might think that this is a good way to sell more Apple's battery is not removable battery, become the norm, more concerned about their status information is a good thing.

Sync: Option keys 10.5 sync icon, you will not see with the normal click any different than yours. Option, click it in 10.6, but you will see exactly when the data type, you simultaneously synchronize each of the last details - this list includes any third-party applications, use, such as sending and TextExpander, synchronization service. You'll also see an open iSync diagnosis of menu items, in order to help resolve any synchronization issues you might have.

As best I can tell, these are the main features of the new options on the four icons snow leopard. Other icons may have been the main features no other choice, or (such as Bluetooth), there is snow leopard, who had the same function. Please feel free to correct me, if you find more new features, but the.
