Which action toggles input monitoring for all tracks that contain an edit selection or a play start marker?

• A. Click track input button
• B. Option-click input button to toggle all tracks
• C. Option+Shift-click for selected tracks
• D. Shift+I to toggle all tracks that contain an edit selection or play start marker

Answer: (D)

In Pro Tools, you can quickly control whether you hear the input signal on tracks while you work, and this shortcut focuses on the tracks currently involved in your edit or playback setup. Shift+I toggles input monitoring for all tracks that contain an edit selection or a play start marker, turning monitoring on or off for that specific set in one step. This makes it ideal when you want to audition live input only on the tracks you’re actively editing or starting playback from, without touching every other track. The other options either affect just a single track or all tracks without considering which ones have an edit selection or play start marker, so they don’t match the described behavior.
