Short description of error
The Annotation tool in the Sequencer(timeline) Sidebar doesn't work, because the D-key is not assigned for drawing, and when assigning it, the annotation cursor is shown, but no line is drawn in the sequencer timeline area.
[The Annotation tool in the Sequencer Preview does not have this problem]
