Seaching using multiple labels
Which key creates the vertical separation between the @abc | @def. I have tried using all the vertical lines on the key board and the search always results in the last label entered.
This depends on your keyboard layout, but usually it's SHIFT and the forward-slash key.
Please check this picture: http://www.commonline.com.au/keyboards/images/us.jpg - here you can see the key between the Delete and the Return keys, it's 3 keys to the right of the "P" key.
