list manipulation - Get brief help for a set of functions

When we are in console mode or working with a notebook we can get brief help about a function just by shift-entering

?function

I would like to have a list like the following

{Map, Function, List, Transpose, Outer, Sequence, Apply, Tuples, \
Distribute, Thread, Equal, Fold, Slot, Reverse, Plus, Times, Total, \
MapThread, Inner, ReplaceAll, Rule, Composition, Through, Nest, \
ToExpression, ToString, Row, Part, Range, ComposeList, Compose, \
SlotSequence, Flatten, FoldList, NestList, Hold, Release}

and get a list of strings containing the corresponding help(s).

? cannot be mapped to a list of course so i am trying to find another way.

? works with Wildcards like ?*Plot* so i suppose it accepts some kind of pattern matching.

Any ideas ?

Answer

Is this what you are after?

#::usage & /@ {Map, Scan}

{Map[f,expr] or f/@expr applies f to each element on the first level in expr. 
Map[f,expr,levelspec] applies f to parts of expr specified by levelspec.,
Scan[f,expr] evaluates f applied to each element of expr in turn. 

Scan[f,expr,levelspec] applies f to parts of expr specified by levelspec. }
