You can do nothing about the mouse - that I can think of,
anyway. The highlight boxes (including properties) as well as
click-boxes, buttons, text-captions and other objects can be saved
to just one or two slides in another movie, then opened in a 2nd
instance of Captivate to be copied and pasted as needed into the
"current" project.
Without criticizing "templates", this simple "Library Movie"
concept is similar but without the confusion-factor that some
people have with templates.
Have a good day!
