I am trying to find a shortcut for marking all messages (eMails) in a folder as read by using a keyboard shortcut, but had no luck in finding one so far.
I am using Microsoft Outlook 2010 and when I open the context menu (right click on the folder), it shows the "e" underlined in "Mark All as Read", which is in my opinion a sign for a shortcut.
Does anybody know the shortcut?
