Right, but turning on is different, right?

I mean, conceptually simpler (slightly).  But that's surely a matter of
taste.

I thought you mean a lighter, but you mean the effect of eldoc mode:
echoing in the echo area with "ElDoc is displayed", correct?

I see that too in emacs -Q, but global-eldoc-mode is on by default, so
this is expected.  You get eldoc echoing when either the local mode is
turned on for this buffer, or the global mode (and the current buffer is
treated by the global mode).  Don't you see this, or do think this
behavior is wrong?


Michael.
