The stacks Window display is selected by clicking on the "Stacks" tab at the top of the large Multi-Purpose Window located at the botton right of the NoteFrog™ program screen. The Stacks Window displays a list of all the user's current stacks. Next to the name of each stack is shown the number of items that stack contains. Among the stacks listed will be the Trash Stack, which is the stack that deleted notes are placed into and held until the Trash Stack is emptied.
Double-click on any stack shown to make that stack become the Active Stack.
