What does the shortcut 'Command + Z' do in Final Cut Pro?

The shortcut 'Command + Z' in Final Cut Pro is used to undo the last action performed in the timeline or project. This feature is essential for editing as it allows editors to quickly revert to a previous state after making changes that they may want to discard. Undoing actions is a common aspect of non-linear editing workflows, making it easier for users to experiment with different edits without the fear of permanently altering their work.

This capability is especially valuable when adjustments need to be made, such as reordering clips, changing effects, or modifying audio levels, as it provides a safety net that enhances the creative process. By being able to quickly undo actions, Final Cut Pro users can refine their edits with confidence, knowing they can revert to earlier versions of their work at any time.
