how to find duplicate transactions?

[David Andel]

Hi all

I've got repeatedly the problem that I have a receipt of something I've
paid and then it's listed also on some of my bank or credit card statements.
Of course I am not going to check the duplicates by hand, so now I'm
left with some transactions being recorded twice in GnuCash - most of
them in different accounts.

How can I check for these duplicates automatically and delete one of them?

Thanks a lot!

David
