Continuing on from a previous Pro Tools tip on using Control to show only the tracks in a particular group here's an idea which, for me, takes this approach to its logical conclusion.
As a Pro Tools user I’ve come to value this show/hide aspect of groups more than any of the other features of mix and edit groups and as a result it occurred to me that I was creating groups specifically and only for this purpose - I was creating groups I would never enable. This is why I sometimes create null groups - i.e. groups with no active properties. Until Pro Tools 12.3 this wasn't available to non HD users as it involves using the Globals tab of the group modify window which was HD only until 12.3. If you are running a version where this isn't available then this workflow still works, just don't enable your group! It's easy to set up. Just go to attributes and uncheck everything. If this is something you think you might do a lot you can save the settings to one of the six available user settings slots and you’ll have group which does nothing except let you show just its member tracks when you Ctrl-click on it regardless of whether it's on or off.
Another reason to create null groups is to associate tracks together for control using a VCA which of course is now available to non-HD users too.
