Tmux is a great replacement for screen, but it's true that keyboard shortcuts are atrocious, I think every shortcuts that I use daily are remapped in my tmux.co

Tmux is a great replacement for screen, but it's true that keyboard shortcuts are atrocious, I think every shortcuts that I use daily are remapped in my tmux.conf. Also when I copy in tmux it automatically change the clipboard and vice-versa, very useful to copy errors or paste snipped of code from internet. And with 'mode-keys vi' it's even faster.
