It was not tongue in cheek. I do not know what cmd is. I assume it is a modifier key in an Apple keyboard, since it is not in a Windows keyboard, which I have (although I am on linux).

Sure, I guess he means search, but he could just say that.

Or should I start talking using references to my keyboard shortcuts? I mostly use emacs, very often with custom bindings, or tmux, so it will not make sense to a lot of people.

But hey, it's a free world.
