How to disconnect from wifi on Mac OS X How does one disconnect from a wifi hotspot on Mac OS X?

The only way I found how is to Turn Wi-Fi off then back on and finally select a different access point...

Surely there must be a better way.
Hold down the option key when you click on the WiFi menu. Then next to the currently active network there will be a "Disconnect from" option. I'm on Yosemite, and so I'm not sure whether this was present on earlier versions of OS X.
