Let me explain this..You are reading a Document and you find an hiperlink who could guide u to any place in the document... Once you are there, you want to go back to the page you were reading...

But how do you make it-.. Actually the only way is to go back and start to search the page where you were placed.. If you are reding just a document of 4 pages , there isn't any problem , but if you're reading a book, for example, it is really bored and stressfull, besides you lose a valuable time..

So i propose a BACK BUTTON. This button simply takes you to the last page seen. So, if you clicked an hyperlink, then you can click the BACK BUTTON and it will lead to the page you were reading....you save a lot of time with this new feature.

This is very usefull, for example, in scientific papers where usually the references are in the last page...and they're related in many parts of the document...
