How can you set all tracks in your Pro Tools session to the same height?

To set all tracks in your Pro Tools session to the same height, holding the Alt key on Windows or the Option key on Mac while selecting track height is the correct approach. This method creates a shortcut that allows you to collectively adjust the height of multiple tracks simultaneously rather than having to adjust each track individually.

This functionality enhances workflow efficiency, especially in sessions with multiple tracks, allowing for a cleaner and more organized visual representation without the need for repetitive actions. By using this technique, you're essentially applying the same height setting across all selected tracks, which can be particularly useful when managing track visibility and workspace in a crowded session.

The other options either suggest using a method that isn't as efficient, such as adjusting each track one by one, or imply that there are limitations on setting track heights, which isn't the case when employing the correct keystrokes to adjust multiple tracks at once.
