type properly, it automatically handles such sequences as single input
events.
Key sequences that consists of @kbd{C-c} followed by a letter (upper
or lower case; @acronym{ASCII} or non-@acronym{ASCII}) are reserved
for users. Emacs itself will never bind those key sequences, and
Emacs extensions should avoid binding them. In other words, users can
bind key sequences like @kbd{C-c a} or @kbd{C-c ç} and rely on these
never being shadowed by other Emacs bindings.
