- While holding down Ctrl key, drag the page and drop a duplicate where you want
You can select more than one page with Ctrl or Shift keys before duplicating.

Note
CorelDRAW X3 will add empty page if you try to duplicate a page that contains a locked object.

In CorelDRAW X4, you can easily find the function under
- Layout menu
- Context menu of the page tab in the Document Navigator (lower left corner of the application window)
