Changing "Junk" to "Not Junk" in Mail

I find many messages in my Junk folder that are Not Junk. I see no way to change their status other than one-by-one. An earlier post on this topic elicited a response that said to select the message then click on the Not Junk icon in the tool bar. I find no such icon. There is one that moves messages to the Inbox. That is also an option in the context menu. I don't want to move messages to the Inbox. I want to mark them as Not Junk.

Thanks,
