Scanning for wireless networks?

Hey,

As I live in Brussels we have many spots here with free wireless, but also with spots where you have multiple options to choose from. Now, with my XP laptop I have this neat 'scan' tool that comes straight of the series '24', I can't find to find anything like that on Leopard here. Is it not built in, should I dl some type of 3rd party app? I have a SR Macbook.

Thanks!

Ps: Is there ANY way to 'maximize' all the apps that have a little blue ball under them in the taskbar? Expose doesn't seem to do that (it only opens those you didn't kinda close with the red X at the top left of the window). The dock is confusing at the moment :-s If the blue ball is still there, this means you didn't quit the app, but it doesn't necessarily mean you have a window of it open either? How the heck?

 

Ah thank you very very much for that

Kis seems very nice indeed, but it says it doesn't work with Airport ? What am I doing wrong?
