Accidentally marked all messages as "read", how to undo?

My girlfriend has an email account with ~10k messages, of which ~700 were unread. Today, while using Thunderbird, she accidentally hit the keyboard shortcut for "Mark as Read by Date", which changed all her messages to read. It's not feasible for her to manually change those ~700 messages back to "unread". Is there a way of making Thunderbird mark those messages as read again?

One thing that occurred to us is for her to select all the message that were changed from unread to read today, then mark all of those as unread. Is this possible.

Thanks! Nate

If you want to change all the messages in a folder to unread:

In Thunderbird thread pane, highlight any message 'Ctrl + A' to select all messages. (You should see a bar with the total number of messages selected, and a brief synopsis of each message.) Now right-click any highlighted message to get the context menu select 'Mark' 'as Unread' Now all those messages will show as unread.
