A few small questions from a new user

[MJ Ray <..hidden..>]

Hi all,

Can anyone point me at the docs for/tell me the Right Way to:
 - save journal lines and account summaries to CSV?
 - issue a multi-currency invoice?
 - edit an invoice after it's posted?
 - run a period end routine? (The manual has Year-end limitations in
section 4.7.4, but a search for Year-end didn't find it elsewhere.)

Sorry if they're dumb questions.  I used SQL-Ledger some time ago,
but I'm pretty sure I struggled with these there too.

Thanks in advance for any help,
