[Answered] Moving Markers

Yes, no problem.
 
1. Select All.
2. Drag across the part of the timeline that contains the material you want to move.
3, Click on a blank space in the topmost track to give it the focus, but make sure you don't de-select the other tracks. Giving the focus pastes everything back to the correct tracks
3. Go Edit > Cut Special. Check both Events and Markers (and anything else that's appropriate, like automation).
4. Place the now time where you want the material to go, and choose Paste Special. Click on Advanced if needed, and make sure that Markers is checked. Click OK - done.
 
You can also move/copy/paste just the markers, which can also come in handy.
