I've been using zsh with oh-my-zsh for several months now with vi commands. Frequently, the command line seems to "lock up" and become unresponsive to input. I chalked it up to some kind of bug, hit ctrl-c, and moved on.
I finally just figured out that I had somehow entered some special mode that activates the "j" and "k" keys to pull up prev/next commands. I still don't know what makes it activate and why it happens.
So now that I know something is happening and I don't know how, it's getting me annoyed. How do I avoid getting into this mode in the first place and how do I properly escape from it without hitting ctrl-c?
<esc>
key is what activates this mode. How do I get out? and better, how do I turn this feature off so I don't get into it in the first place?
