Paste as Workbook Document - As Prior Sibling
Select Paste as Workbook Document - As prior sibling from the Workbook Tree shortcut menu (accessible by right-clicking in the workbook tree area) to paste the contents of the Clipboard before the currently selected item in the workbook tree. Note that if the top level of the workbook is selected, this command will not be available as it is not possible to paste anything as a sibling to the first folder in the workbook tree (i.e., on the same level as the root node).
To use this command, you must have an acceptable workbook item on the Clipboard (e.g., a folder, STATISTICA or other ActiveX document, or another workbook). If the Clipboard is empty or if you have copied something else (e.g., text from an e-mail message) to the Clipboard, this command will not be available.
