An ultimate productivity key-binding in tmux is one to switch to the last session. I use this to quickly get between sessions really quick. Often I am working and need to lookup a quick note, or copy something into my notes, then get back to where I was quickly.

bind -n M-b switch-client -l

I think of this hub and spoke model, and use last-session to quickly drive it.
