100% Annoying, serves no purpose what I can see and messes
up alignment/indentation, even.

I have some code, here


which doesn't bring up the *Help* buffer but echoes the char's
names (new and old, often, e.g. / is

  solidus (old: slash) (at point: 1308)

so yes, we're all old-school I think ...

Anyway ... one could bind that to just a single key,
optimally, or even do with the idle timer (it could be
instructed so if the key is showable in the Linux VT it
wouldn't echo anything).

Also, those chars shouldn't be everywhere anyway, right?

But I agree diamonds were much neater and low-key ...
