Both Vim and Emacs can bind almost any(1) kind of input with the right configuration. Emacs has a lot of them in the default configuration, Vim just a bit using e.g. the leader key and Ctrl-W for window/split navigation. But in the end it's about efficient keyboard-focused controls and it seems for many WordStar was the first one that fit the bill.
