What is the difference betwenn runtime and edittime?
At edittime you define the presentation. You can manipulate all elements on a slide. You define the appearance and behaviour of the presentation. If you change to runtime the presentation starts running. All settings you have done at edittime will be applied now. All action scripts you have defined will be executed only at runtime. At runtime you can also use the AutoWalk function to automatically move forward/backward with the RETURN and BACKSPACE keys.
