Help for User navigation

Thanks for your quick response.  I will try this!

HTML5 compatibility means no rollover slidelets. You can create a caption and other objects on the first slide, time them for the rest of the project, check that they'll always be on top, and group them. Make the group initially invisible in output (if you use CP8: the eye icon in the Properties panel). I will label that group: Gr_Help

Create a Help shape button  SB_Help, because that is the only interactive object that can be put on master slides. That button will have a toggle functionality. Create a user variable v_visib. It will be used to track the visibility of your Help group, you can give it an initial value of 0. Create a conditional advanced action, will label it ShowHelp:

IF v_visib is equal to 0

    Show Gr_Help

    Toggle v_visib

ELSE

    Hide Gr_Help

    Toggle v_visib

I would recommend to create another standard action to be triggered  On Enter for each slide to hide the Help if it is still open:

    Hide Gr_Help

    Assign v_visib with 0

If you want the Help button not to have the same look when Help is open, have a look at the scenarios here
