Homebase for Sonar users

Thanks JM…the command I’m looking for is one that decreases all the track heights so that they fit the screen. If there are 3 tracks, their height is reduced by just a little so they fit. If there are 10 tracks, their height is reduced by a lot so they fit. One command. It would seem that there is such a thing in keyboard shortcuts called “agents:show all channels/tracks” but it does nothing that I can see. Must be a command for the visibility panel.
Your solution takes too much time because you have to click on each track to get them all to fit. What I’m looking for is a “one key” solution. I’m surprised if Cubase doesn’t have it. More likely that I don’t know what to call it to look for it in keyboard shortcuts.
