thanks for the info.

I've downloaded the SlingPlayer DMG file and tried to find out which 
shortcuts can be used. As IOSPIRIT is based in Germany and we don't 
have access to a SlingBox here, my possibilities to find about them 
are very limited, though.

I'd love to provide an updated version of the SlingPlayer Behaviour, 
but would either need a list of keyboard shortcuts that work for it - 
or temporary access to a SlingBox over the net (my understanding is 
that the SlingPlayer streams the media of your SlingBox over the 
net), so I can actually use, test and work with the interface of the 
SlingPlayer app.

Best regards, 
Felix
