on the ribbon tab Formula | group Watch.
If you choose this command again, the window will disappear.

| Tip: You can also enter an entire cell range here. For example, if you enter A1:A3, the cells A1, A2 and A3 will be added. |
The content of the specified cells is now displayed in the watch window. Whenever the table is recalculated, the watch window will be updated as well.
