What keyboard shortcut is used for zooming in and out of the timeline?

The keyboard shortcut for zooming in and out of the timeline in Premiere Pro is indeed represented by the letter Z. This shortcut activates the zoom tool, allowing users to click on the timeline to zoom in on specific areas or hold down the Alt key (or Option key on Mac) while clicking to zoom out. This functionality is crucial for detailed editing, providing a clearer view of the clips and their arrangements, enabling precise adjustments to be made.

Understanding how to efficiently navigate the timeline can significantly enhance the editing workflow, as it allows for quick transitions between different levels of zoom to facilitate both broader overviews and meticulous edits. This makes Z a pivotal shortcut for anyone working with complex timelines in Premiere Pro.
