Is it possible to scroll with mouse similar to vim?
You can scroll the file list with mouse. Did you mean the preview window?
I am using VIFM in a tmux session and I just realized that I can scroll the file list outside of tmux. Thank you. With VIM, I can use mouse even inside tmux. I am wondering if there is any configuration that I can play with to make the mouse scroll working inside tmux?
Mouse is not handled. There were attempts, but it never worked well. Actually it worked horribly with mouse events disappearing or happening after you did them.
