how to open 2 pages of a document at the same time

[Dr. Rudolf Alexander5C80]

Hello,

How can I have 2 pages of a PDF document on my screen? E.g., a text page and the reference list, which is at the end of a manuscript. There should be a way of dividing the screen.

Many thanks in advance

Alexander
