Thanks, I will do that.

yes, it was customizable (using the way Kevin Rodgers suggested), but
I ran into the above RET problem you mentioned myself, and made TAB
the default in 0.2.

Hm, on my emacs 21.2 and 21.3, it never seems to get activated in the
minibuffer in the first place for some reason, but i will go ahead and
provide something like an "expand-in-minibuffer-p" option, and disable
it by default.

Ah, I don't understand dabbrev.el too well, so I was not sure if
dabbrev-expand will expand to the same completion as shown by
dabbrev-hover.el (which, of course, dh-complete does, by
construction.)  dh-complete also makes the code general enough to
allow use with other mechanisms like hippie-expand, as suggested by
Trey Jackson privately.

thanks, done in 0.2dev already, with help from Uwe Brauer.

It does :)

Will add.

One thing I don't understand is why fancy dh doesn't work when in -nw
mode (emacs -nw).  Everything in the code/edebug suggests that we are
in the right mode (dh-fancy-doing-mode), yet it doesn't work..  even
when I do the following for debugging:


 
 (define-key dh-fancy-doing-mode-map (kbd "t") 'dh-complete)
 (setq dh-fancy-doing-mode-string " DEBUG")

and then try "t" for completion.  
I would be in the dh-fancy-doing-mode, yet t will
 self-insert... strange..
If anyone knows, please do share..

(manual M-x dh-complete still works)
