* cl.texi (For Clauses): @items for hash-values and key-bindings

to make them more visible when skimming.  Add examples of `using'
clause to them, examples being clearer than a description in
words.

or @code{while}.
@item for @var{var} being the hash-keys of @var{hash-table}
This clause iterates over the entries in @var{hash-table}. For each
hash table entry, @var{var} is bound to the entry's key. If you write
@samp{the hash-values} instead, @var{var} is bound to the values
of the entries. The clause may be followed by the additional
term @samp{using (hash-values @var{var2})} (where @code{hash-values}
is the opposite word of the word following @code{the}) to cause
@var{var} and @var{var2} to be bound to the two parts of each
hash table entry.
@itemx for @var{var} being the hash-values of @var{hash-table}
This clause iterates over the entries in @var{hash-table} with
@var{var} bound to each key, or value. A @samp{using} clause can bind
a second variable to the opposite part.
@example
(loop for k being the hash-keys of h
using (hash-values v)
do
(message "key %S -> value %S" k v))
@end example
@item for @var{var} being the key-codes of @var{keymap}
@itemx for @var{var} being the key-bindings of @var{keymap}
This clause iterates over the entries in @var{keymap}.
The iteration does not enter nested keymaps but does enter inherited
(parent) keymaps.
You can use @samp{the key-bindings} to access the commands bound to
the keys rather than the key codes, and you can add a @code{using}
clause to access both the codes and the bindings together.
A @code{using} clause can access both the codes and the bindings
together.
@example
(loop for c being the key-codes of (current-local-map)
using (key-bindings b)
do
(message "key %S -> binding %S" c b))
@end example
@item for @var{var} being the key-seqs of @var{keymap}
This clause iterates over all key sequences defined by @var{keymap}
