"TUAW-lover Andrew accidentally discovered that if you select a file in the Finder and press Apple + Shift + B (aka Command+Shift+B), it brings up the Bluetooth File Exchange application and prompts you for which device you want to send the selected file(s) to." *
This tip is a life saver! I use bluetooth connection on daily basis and I cannot afford having to turn the bluetooth ON, selecting what files to send, searching for devices and send them over each and everytime.
Just note that, depending on your applications and their shortcuts, this tip might not work with you or might give you other actions.
"Click on Finder > Services and you should be able to see all the shortcuts"
