Can't you use ginput(0) for these cases?
It doesn't work on Mac with no middle mouse button to terminate the
sequence, but that is a separate issue.

The cases I'm thinking about (e.g., select fit range) have a specific
number of points. Other cases (e.g., select shape outline) have an
indefinite number of points. I can't think of case off hand where
I would want e.g., six or fewer points.
That said, I can always wrap the function in my own interface for my
scripts.
