OK.

IMO, using slant for a defined term in print is not too good, and having the
same appearance for defined terms and emphasized text (unrelated) is also not
too good. I'm a bit surprised, frankly, given the fine-grained print
representation of things like keys - by contrast, this seems rather coarse. But
if this is the long-established Texinfo convention, so be it.

Here are some possibilities for defined terms in Info - that is, terms that are
defined in place (whether or not they are also listed in a separate glossary). I
assume that both "..." and _..._ will continue to be slant in print. And I
assume emphasis in Info will continue to be shown using italics.

* italics
* bold
* underlining (not underscore wrappers)
* some other face (e.g. color)
