     West points out that the character % in command escapes is expanded
to the current filename.
     If one only wants to _s_e_e the current filename, the command
^G  or  :file<CR>  will show that.  But if one wants to get it into the
file (other than by copying by hand from the bottom line the result of
one of the above commands) then an application of the feature West
mentioned is needed.  The command
	:[address]r !echo %
seems the best way.  It can be used in editor scripts as well as
mappings.  The disadvantage is that shell escapes are slow.
And a general disadvantage of using % is that it shows the current
file name *as one originally called it*, not in any uniform format --
It will be shown relative to the directory one was in when one
entered vi, unless one used an absolute address or called it relative
to one's own or another's home directory, in which case it will have
an absolute address.
