Move through display levels
The windows in a Logic Pro project have several display levels, with the Tracks area at the highest level, and the editors normally at the lowest level. You can work on different types of tasks, such as arranging the overall project or refining individual regions, at different levels. In many cases, you can switch between these different levels directly, without needing to open or access another window.
Move one display level higher
Do one of the following:
Click the Display Level button in the upper-left corner of a window.
Double-click the background area of a window.
In the Piano Roll and Step Editors, a step up the display hierarchy shows the events of all regions in the Tracks area.
In the Event List, clicking the Display Level button moves you up one level in the display hierarchy. The display remains much the same but shows a list of regions, rather than a list of individual events, along with region positions, names, track numbers, and lengths. The MIDI region that you were just editing is selected within the list of region names.
In the Score Editor, clicking the Display Level button takes you to the higher display level. Double-clicking a staff (at an empty point), reverts to a lower display level.
