I'm trying to expand a timeline marker by Alt+Clicking on it and dragging it to the right, but it's not working. I've watched several Premiere Pro tutorial videos demonstrating this action, but when I hold down the Alt key my mouse cursor turns into a little hand and does not allow me to span the marker. Any suggestions? Thanks.
Thank you for the suggestion, Ann Bens. Yes, if I drag the Duration value in the Marker dialog it creates spanning marker. That's what I need. I also discovered that if I change the Marker type to Chapter it allows me to create the span using Alt+Click, but not when it's a Comment Marker.
