Use the mouseLine function within a handler to determine which line the mouse is hovering over, in order to take some action based on the click.

Value:

The mouseLine function returns a chunk expression of the form line lineNumber of field fieldNumber.

Comments:

The mouseLine function only returns locations in a field. If the mouse pointer is not over a field, the mouseLine function returns empty.
