[FinalBuilder Professional Edition]
The Stack/Queue Peek Item action is used to retrieve the next item from the list and set a variable to the value without removing the item from the list.

Stack/Queue name - select the name of the list which you want to peek. If there aren't any items in this list, you need to use the Stack/Queue Define action to create a new list.
Peek to Variable - select a Variable to set to the peeked value. The item will not be removed from the list.
Expand variables - this will expand any variables in the item after it has been retrieved.
NOTE: If there are no more items to peek, then the action will fail.
