Re: Icicles doc - file 1/2 (was: propose adding Icicles to Emacs)

    ;;  You can get the standard Emacs "prefix" completion, instead of=0A=
    ;;  this "apropos completion", by using `TAB' instead of `S-TAB'.  You=0A=
    ;;  can cycle prefix-completion candidates by using the `up' and=0A=
    ;;  `down' arrow keys instead of `next' and `prior'.=0A=

That feature has a conflict.  `Up' and `down' in the minibuffer move
thru the history; that works for all minibuffer arguments, with or
without completion.  So if we are to install this feature, it needs
to be on other keys.

    ;;   C-h f  c h a r  S-TAB - display all function names that contain=0A=
    ;;   `char'.=0A=
    ;;=0A=
    ;;   M-*  d e l e t e  - narrow that set of names to those that also=0A=
    ;;   contain `delete'.=0A=

I wonder if it would be more convenient to interpret
some syntax for this, such as `char&delete'.

Meanwhile, it seems to me that Icicles completion is something like
Dired, and it might be useful to generalize it to allow marking
completion alternatives and unmarking them, so then you can say
"Operate on all of these".  That could be a lot more convenient than
submitting them one by one as arguments using the multi-command
feature.
