How to scroll individual blocks of a webpage in VKontakte without a mouse ?? More specifically, in the "dialogues", I can not scroll through the chat window with friends. I know how to scroll the page without a mouse in general and specifically the dialog, but I can’t select a separate chat selection block. Thanks in advance.

Answer 1

У меня скроллится
and all without a mouse :)

Answer 2

First you need to select a block using Tab and arrow keys, this usually works, but it may not be highlighted in any way when focused, which makes it difficult to find.
