In Icicles:

* `C-h v map S-TAB' completes to variables whose names contains "map".

* `C-h v map TAB' completes to variables whose names start with "map" (just
as in vanilla Emacs).

* You can use `M-*' to match against multiple patterns (e.g. "map",
"mode",...) - as many as you want. So, for example, `C-h v map M-* local M-*
mini' completes to variable names that contain "map", "local", and "mini",
in any order.

* You can use `C-~' (complement) to remove matches. So, for example, `C-h v
map M-* local M-* mini C-~' matches variable names that contain "map" and
"local" but do not contain "mini".

* You can use regexps, not just substrings, as match patterns for `S-TAB'.
So, for example, `C-h v [^-]map' completes to variables whose names contain
"map" following any character except `-'. And `C-h v map.' completes to
variables whose names contain "map" but don't end in "map" (more precisely,
contain "map" followed by a non-newline character).

* The same completion features are available for any kind of completion:
buffer name, file name, command, and so on. So, for example, `C-x C-f map'
completes to files whose names contain "map".

* You can use `C-M-mouse-2' to get help about selected completion candidates
on the fly, before choosing one to use. So, for example, `M-x map S-TAB'
followed by `C-M-mouse-2' on selected completions in buffer *Completions*
prints the descriptions of those clicked commands (whose names contain
"map") - as many as you like, in any order. (Hit `RET' to finally choose one
to execute, or hit `C-g' to cancel.) Or, for example, `C-x f ab TAB'
followed by `C-M-mouse-2' on selected file names (which all begin with "ab")
prints file properties (file type, permissions, size, times, etc.).

Icicles has a lot to offer, and the doc describes it all, but the basic
features are simple to use - you can take advantage of them without reading
any doc. And `C-?' during completion gives you summary help.
