Quick Watch Window

Only available when in break mode
This window is similar to the Watch window except that you can only add one variable to this window.
When you are in break-mode you can right click on a variable and select "Quick Watch" to add it to this window.
If you want to see the value on an ongoing basis (??) then you need to add it to the Watch WIndow.

You can also display values by hovering over the variable or statement with the mouse and using the DataTips pop up window.
