When reading math papers, jumping by hyperlinks in pdf file always make me tired.
For example, "By Theorem 1.1 we know that the functor is exact balabala...", in which Theorem 1.1 is a hyperlink which will jump to the real Theorem 1.1 in this paper when click on it.
However, The text I'm reading is in page 400 but Theorem 1.1 may be in page 20. So after I read the fulltext of Theorem 1.1, I have to get back to page 200, by operating the scorebar or input the page number, which is not convienient enough, especially when I only need to have a glance on Theorem 1.1 instead of reading it carefully.
So if when I hover over the hyperlink, a floating small window, showing the content of the hyperlink pointing to, can popup, and can disappear when moving the mouse to somewhere else, it will be much better.
My question is, whether a pdf viewer supporting the described function or something similar exists?
