Re: snarf up text when at query-replace from: prompt

well actually lets talk about C-s.  If one hit C-s C-h, wouldn't it be
neat if it were like when one hit C-h k C-s?  At least give some hints
in the minibuffer about goodies like:

Type C-s to search again forward, C-r to search again backward.
Type C-w to yank word from buffer onto end of search string and search for it.
Type C-y to yank rest of line onto end of search string and search for it.
Type M-y to yank last killed text onto end of search string and search for it.
etc.

this would appear as "C-s, C-w, C-y.... C-h for more info" in the
minibuffer.

Do something similar when one hits M-% C-h, of course offering the
choices I propose below.

ah, but setting that variable back and forth is quite inconvenient.
I say the from and to stings should be able to be vacuumed up with
things like those 4 above... just like C-s... hmmm, true we are
sitting in the minibuffer and not in the main window like with C-s.

Anyway, a start would be if M-% C-w would copy the word we are on into
the From string..  More C-w's would add more to it, like C-s....
Hmm, then there's the To string... well, we would have to reposition
the cursor usually.... bla bla bla... anyways, C-s is quite high
powered vs. M-%...
