But this sentence is not correct:

"It [i.e. STARTKEYFUN, added by me] may return either a non-nil value to
be used as the key, or else the key is the substring between the values
of point after STARTKEYFUN and ENDKEYFUN are called."

This is the sentence that misled the OP I think.  Could we be more
precise and tell that the key is actually the cons cell (BEG . END)
denoting these strings?


Michael.
