Drag the analysis up or down. You can only move analyses within the same branch. This does not affect calculations but can help you reorganize your document.

If you want to swap a higher analysis with a lower one (higher/lower in tree hierarchy), you can right-click on the analysis and click on 'Move up'. Note that you can do this only if the lower analysis isn't accompanied by other analyses.
