One of my difficulties has been using the tramp manual. To illustrate
this, here's a quote from it:

In context, the string "password-cash-expiry nil" would have to be for
tramp or emacs. I see no place one would put it for tramp, and so I
assume it is an emacs lisp expression. If I knew this was meant to be
part of an emacs lisp expression, I would then know it was irrelevant
to a tramp list ;-)

The tramp manual does not state explicitly one can't provide a URL for
a directory for a text file, and otherwise, the word "file" in the
unix world can mean either. True, all the examples happen to use a URL
for a file. 

In the directory on the ftp server in which I arrive via tramp, there
is the "html" directory that I use. It is drwxrwxrwx usr1066:usr1066. Since
I'm "usr1066," I should have no difficulty accessing that directory. Your
question implies I should in fact be able to access it, but others
appear to say, no.  

I tried address@hidden:/html, but tramp can't see the html
directory. I suspect I need to figure out the path to that directory
by first running /address@hidden:/ and note the steps I need
to take to get into html.

This is resolved, thanks. I ended up defining a variable in emacs
because that resulted in the least typing: C-x C-f $target.

Thanks for all the help. I did file up and downloads from the server
today as an exercise, and it worked very well.
