Moving Items Using Cut and Paste
Select the items you want to move and click Cut. The selected items are deleted from their original location and placed on the clipboard.
Click Paste to paste those items in the original one-line. You can also open another one-line window and paste the items there. Any time you paste items, a dynamic image appears in the upper-left corner of the active one-line window. You can drag the dynamic image to where you want it on the one-line, and then drop it by clicking somewhere outside of the image.
