Quickly Enable & Access Lion’s AirDrop File Transfer with Command+Shift+R
Remembering a keyboard shortcut makes using AirDrop even easier, by quickly accessing the AirDrop window and enabling the Mac to be ready to accept or send files.
The AirDrop keystroke is Command+Shift+R to instantly bring up the AirDrop window from anywhere on the Mac OS X Lion desktop.
Remember that all Macs must be in the AirDrop window in order to work with each other. The shortcut should work with AirDrop on unsupported Macs as well.
