I just had the idea of having marks in ecasound. so that you could set them
and use them for finding certain positions. I thought this commands might be
necessary:
cs-setmark - set a mark at a specific position
cs-remove-mark - remove the selected mark
cs-goto-mark - goto the selected mark
cs-play-to-mark - just play from the current position to the selected mark
(to
see if it is set correctly)
cs-list-mark - list all the marks with their positions
