Activate, deactivate tracks on timeline

Hi all, I was looking for a way to lock a audio clip on a track I thought already exist that feature... somthing like RMB "lock clip" or so. Instead of that it would be useful a way to activate deactivate a whole track. Let say a button on track's header o a little menu on RMB with "activate all tracks" "activate this track" and "activate this track but all others" or something like that.
I think this can speed up our editions, at the moment I find a little difficult to move lots of video clips letting an audio track on its place.
Regards :D

You can lock a whole track, it's one of the three icons under the track name?

OH! oops!
I confused the icon with a clapboard... :S
Thanks yellow
