No, *that* isn't.  The reason why I didn't even consider that is that I
really hate it when (familiar & frequently-used) commands start asking
additional questions like that.

Some folks want some new behavior.  I agree that the posssibility of a
download-like function that may take from a cache makes sense.  But I
don't see why this has to be grafted onto the existing DOWNLOAD key
command.  'd' is already doing double duty, as a "proper" download
command and as part of a circuitous "download the current document"
recipe.  Maybe it's time to make that latter one unnecessary, by
creating a DOWNLOAD_CURRENT_DOC key command.  That could naturally
have different semantics w.r.t. caching.

Why are we discussing this anyway?  It'll enter lynx-dev history as
another pointless, ineffective, theoretical discussion unless
someone's going to write code (and I'm not volunteering, I don't think
you are, I don't know about LP or PG who brought this up).
(But making a new DOWNLOAD_CURRENT_DOC function and adding try-to-use-
cached-doc-copy functionality to it may actually be simpler to implement
than adding try-to-use-cached-doc-copy to the current DOWNLOAD[_LINK]
