tmux splits shells into windows. The suggested workflow is to have vim in one split window, and other shells in other windows. tmux has the benefit of a keybaord-driven interface to jump between terminals, so it's not unlike having Emacs running with various vertical and horizontal splits running console buffers (which is something Vim doesn't support well natively.) It gives Vim users the kind of workflow that some other tools provide natively with a completely keyboard-driven interface.
