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.
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).
