If you add flags you can do this using the TAB (forward through timeline) or SHIFT+TAB (backwards through timeline). Add a flag by showing Project in the timeline, then click on the Project button, then you'll see a flag icon next to the 3D Motion Angle Alignment icon. Give it a name and apply.

just short question.
is it possible to make the timeline-marker snapping to end or start, or general to a marker. Its time intensive to scroll 10 times to line them up.
i hope this is a tool i just missed, would be nice if some one can navigate me how to snap time line so i didnt scratch marker far away.

thanks
