[Evolution] Feature request if not already implemented

[Jon Reynolds <jonr destar net>]

I am wanting to be able to mark all my folders for various mailing lists
as 'read'. To do this I have to go to each folder and use the 'ctrl a'
then 'ctrl k'. Is there a way to do this in one easy command? If not
would it be difficult to add?

Thanks for any replies,

Jon
