while working with speed ramping once I have put a blade marker in I can't work out how to:
1.remove it (apart from immediate undo, i.e. later on)
2.move its position in relation to the src clip, i.e. I put the blade point in the wrong place, I want to move it without adjusting the retiming either side of the point
3.join adjacent retimed segments... related to above, if I put in a new blade point in the correct position I can't remove the wrong one (1) or see a way to join/merge the adjacent retiming segments
thanxx for help!
