problem with new marking interface
- in the custom marking list, one cannot delete markers once they have been entered (there is an 'add marker but no 'remove', clear erases all)
- the control+click is a bit difficult; in order to activate the ctrl+click option, one has to move a bit the mouse, if not it will go global. sometimes, even moving does not make anywave understand we are in "target" mode , it sets the marker as 'global' whatever we do
- it would be nice to be able to delete a marker with a shortcut
