[runcoms/zpreztorc] Suggest changing the key timeout for vi mode users

Set the time for zsh to wait for additional keypresses. In vi mode you
should set this to 1 (0.1s) to remove the delay from entering and
exiting vicmd mode. The default is 0.5s.
Recommended in vi mode, but setting too low in emacs mode will not allow
time to enter additional keypresses.
