What is the current zle keymap/mode?

For example, if I hit the right combination of keys to enter viins and walk away from the terminal and forget, how can I tell when I get back? How can I tell what the default mode is? The guide has this: > If you’re in the wrong mode, ‘bindkey -e’ in ~/.zshrc takes you to emacs mode and ‘bindkey -v’ to vi mode. But what *is* the mode? I'd like to know before typing. The $KEYMAP special variable is, as far as I can see, only available *within* zle widgets, and I can find nothing in man zshzle nor the zshell user guide as to how to tell what the current mode is. Any help or insight will be much appreciated.
