Coming from Logic where, if I clicked on an instrument track’s “header”, every region contained on that track would highlight. This is super helpful because it allows me to see, at a glance, if a given track is populated by regions, and where. Is there a preference in Cubase to toggle a similar behavior?
Unfortunately this is not possible. You can right-click to the track and select Select All Events from the drop-down menu. Of course you can assign a KeyCommand to this function.
For what it’s worth if you double click with the Object Selection tool it will also select all regions from the region you click on to the end if that helps you at all. That’s a function I use regularly, it also allows you to move the regions rather than just range select them.
