How can I put my MacBook Air into clamshell mode when it's open and working?

I can put my MacBook into clamshell mode by just close it and sending some USB/Bluetooth signals. However, sometimes I want to get into the mode directly without those actions. Is there no button or menu written "Get clamshell mode now"? Or utility?

I was charging my iPhone last night through my laptop (in a foreign country), and I closed the lid on my 15" Macbook Pro... When I unplugged my iPhone from the USB Port this morning, I heard the hard drive turn on, or maybe it was just the fan, but…
