Many thanks Adam,
I thought I'd tried editing the pdf after signing it to test that out,
but obviously failed!
but I can see that works now.
thanks again for the explanation.
I'll try playing with gpg --verify now too.
It was also kind of you to respond so quickly.
all the best

In an openoffice document you can sign a document with a digital signature,
and it's all contained within the document.
That's a signature performed with an X.509/PKCS #11 certificate
provided from your mozilla store and placed in the .odf, etc.
according to the specification of that file.
Right clicking on a document in Gnome, produces a menu-item "Sign" - which
duly produces a .sig file. with seahorse
..so what do I do with it? ;-)
This is a detached signature generated from a GPG/PGP key. Double
click it and you should get a notification or dialog indicating the
status of the signed file. It should be distributed with the signed
file. You can also do gpg --verify foo.sig or seahorse-tool --verify
Have I just got the wrong impression, and the signing of a file is for
signing other certificates to make them "trusted"
or should I be somehow embedding the signature file within the pdf?
Unless evince or OO.o understand how to sign a pdf themselves, it
won't be included in the file.
