I am using the lists like groups. I would like to copy / paste quickly contacts from one list to another. Or, I would like to select contacts in one group and save them in a new one. How can I do this.
You can copy one or several entry from a list (Edit -> Copy) then select another list and paste them (Edit -> Paste). You can also select a bunch of entries and use the Recipients -> 'New List From Selection' menu.
