Thanks for "export KEYTIMEOUT=1"!

I use https://github.com/robbyrussell/oh-my-zsh which has a nice vi-mode plugin, built in indicators like you mentioned too

A terrific fork of oh-my-zsh is Prezto.

even for guys who's not considering to use oh-my-zsh it worth to check internals of https://github.com/robbyrussell/oh-my-zsh/blob/master/plugin...

KEYTIMEOUT is in hundredths of seconds. So this sets it to 0.01 seconds, not 0.1 as the article claims.
