Is it possible to have a link in a page you are reading say "page 1" and when you are on the page you linked to "page 2", have it return to "page 1".
But also when reading a page in the same book say "page 7" with a link to "page 2" and when you are on "page 2", have it return to "page 7"

I guess my questions are;
1. Am i dreaming?
2. Is it possible in an epub?
3. If possible in an epub would the same epub convert to other formats and still work if converted? (kindle, Apple etc)?

Apologizes if this has been mentioned before, I do not know the terminology of what I trying to do when searching and have been going around in circles.

Thanks for any help you can give
