Hyperlinking 'back to'
yes, Atul was right.
If you are in a web page or MS office, write 'back', and hyperlink to required / mother/previous page. This is what I understand. I use this to come back to slide 'x' from slide 'x + 1delta x ' while the next slide were y. That is if some student asks me to say, explain a definition / or explanation for a term, I open up the subroutines "delta x's 1......n" . In normal course I would have encountered ' y ' slide after 'x', where from I do come back with back button on the tool bars. So Hyperlinked back enables you to skip pages.
