If you want to navigate through the target semels of any 1-to-many association, you can use a "to-do" list.

Click on the "To-do" button of that association.

This copies the sequence of target semels into an internal buffer.

Start with the 0th target semel (Edit menu choice "Go to the current to-do").

You can navigate forwards (i.e. higher-index) (Edit menu choice "Go to the next to-do")
or backwards (i.e. lower-index) (Edit menu choice "Go to the previous to-do")
through the target semels.

There is only one "to-do" list at a time. If you start a new one, then it replaces the old one.
