Unbound? What is that?

Can see what you mean.  That although what happens in the actual buffer
is local to the buffer, how the cycle performs, would depend on what
was done on other buffers, creating confusion.  Actually, it is not very
confusing as I write what option was selected in the mini buffer.

I have now started to understand buffer local quite well.  It has been
occurring to me that most things really got to be buffer local.

Continuing with the keybinding cycle (pressing repeatedly a key-sequence
to switch configuration, e.g. auto-fill in my case).

I am really getting into some difficulty figuring out what commands
would one want to have a Keybinding Cycle that would not be buffer-local.

For what things should a key-cycle be global?
