open Explorer and select a folder in the left pane. Next, using the cursor keys, navigate to another folder in the pane, then press Delete. Select No in the resulting confirmation dialog box to cancel the folder deletion, then quickly repeat the navigation, deletion, and cancellation steps. If you repeat the steps quickly enough, Explorer will fail to notice that you've navigated to a new folder, and instead ask you to confirm deletion of the last folder selected. Choosing Yes in the deletion confirmation dialog box in fact deletes the previously selected folder.
