What happens when you click the cursor in the Edit Window?

When you click the cursor in the Edit Window, the primary action that occurs is marking an edit selection at that location. This functionality is fundamental for editing tasks, as it allows users to precisely define which audio or MIDI material they intend to manipulate or process. By clicking in the Edit Window, you can easily set the starting point for an edit, making it more intuitive to select and edit specific sections of your audio tracks.

While other actions might occur in a typical workflow, such as the playhead moving to a new position, the essential response of marking an edit selection is what enables effective editing. The ability to specify an exact point for edits significantly aids in performing tasks like cutting, copying, or pasting audio clips. Thus, the focus on marking an edit selection directly reflects the core functionality intended in the Pro Tools editing environment.
