Shift+M takes you to the beginning of the next marker in the clip/timeline.

Make it a user option to let Shift+M also stop at the END of a marker.

I use markers extensively and once they are set up I always cut at the beginning and the end of these. Having a short cut for stopping at the markers end will speed up the process.

....a small step for mankind, a giant leap for .... well, at least me :).

Thanks
