SHORT CUT KEYS on 945

maybe you misunderstand the question... I'm talking about the HRM CHEST BAND setting as an short key selectable, which is currently not visible in the list of avaiable functions

With a HRM band, it doesn't connect to the watch until you start an activity (or run something that specifically tries to connect), and when you end an activity, it disconnects.  When you decide to use an HRM band, all you really have to do is put it on and take it off when you're done.

Settings-->system-->shortcut keys

What I'm saying is I'm not sure you'd need it, as you really don't have to change anything on the watch when you use an external HRM. It's automatic.

yes I know it is automatic. What I would like to set is the possibility to switch off the automatic search of the band... as this is a source of draining battery. Is it now clear?
