Welcome to the forums. I don't think there's a way to have
back and forward buttons in the skin itself without tweaking the
skin files. A couple of things you could do instead:
1. Create a browse sequence, though the back/forward buttons
that this adds to the skin don't do the same thing as the browser
buttons. They would move the user forward or backward along the
browse sequence.
2. Add some JavaScript to back and forward images in each
help topic. Do a Web search for "JavaScript back forward buttons"
and you'll get a lot of results for how to make it work. If you
already have topics, you would probably want to use a find and
replace tool to add the code to each topic if you don't want to
manually go into the code of each topic to make the changes.
Hope this helps,
Ben
