Macro info

I've been using nano for decades (GNU/Linux) but only recently discovered t=
hat it is able to record and run macros, something that would be quite help=
ful to me at the present moment. It is clear to me how to record, then repl=
ay a macro, something I've already tested out. But I'm having trouble findi=
ng further information about this feature. For example, can I record more t=
han one macro? If so, how do I recall/replay the various macros I've record=
ed? If anyone casn point me to further information on this feature I'd be g=
reatly appreciative. Thanks=
