As you arrange the objects on your form, remember to use the Undo and Redo tools to correct mistakes.

You can use the Cut , Copy , Paste  and Paste At  buttons on the toolbar to duplicate a selected object or group of objects.

When pasting an object from the clipboard, Paste places it directly on top of the cut or copied object, however you can select the location for the new object by clicking the Paste At button and selecting the location for paste.

The Duplicate command (CTRL+D) in the Edit menu makes a copy of the selected object or group of objects and slightly offsets it from the original.

You can also duplicate an item using the CTRL key and drag and drop. While holding the CTRL key down click the object to select it. Holding the left mouse button down drag the new object to a different location.
