Zoom Vertical Out    ⌘↑

Reduce the vertical size of the display. In the Score Editor the entire page shrinks. In the Arrange window track/region height is reduced.

On the X-Touch press the “cursor” key (center of the direction arrows) and use the up-arrow.

None of the documentation describes the result of the action very well. Experimentation is the way here.

Scroll and zoom the Logic Pro Tracks area — Apple Support

In Logic Pro, drag the horizontal and vertical zoom sliders in the Tracks area menu bar. Drag the horizontal slider left to zoom out for a wider view, or drag it right to zoom in for a close-up view. Drag the vertical slider up for a wider view (more tracks), or drag it down for a close-up view (fewer tracks).
