I have bluetooth headphones which I use to both listen to music from my mobile phone and to listen to videos on my laptop. They cannot be connected to both devices at once (note here), so I have to disconnect from one device before connecting to the next device.
To do this on Windows 7, I have to open Devices and Printers, open my bluetooth headphones, and click on the Connect/Disconnect button. I'd love to be able to run a script that triggers that Connect/Disconnect button. That way I could have a shortcut on the desktop or add a keyboard shortcut.
I've streamlined it somewhat by creating a shortcut to the bluetooth heaphones window (in Devices and Printers, right click on your bluetooth device and choose Create Shortcut). But it would be good to streamline further.
