working first time in full screen mode (shortcut "ü" (German version)) I accidentally added markers within a clip of the timeline and not in this timeline itself.
Is there a possibility to "transfer"/move/copy the markers into the timeline? Or only by making complicated changes in the XML code of the prproj file?
Gang the Source Monitor to the Program Monitor and work your thru the Markers.
... after looking into the source code ... I rebuilt the markers in the timeline manually -- while moving the "playing marker" (German: Abspielmarke) I set the markers via "m" (in a zoomed view of the timeline and in fullscreen to "hit" the markers in the clip as exactly as possible...).
