There are six items listed under the Edit main menu plus an additional four when editing a card.  They are as follows:
 

Undo	This gives you a second chance when you make a mistake.  It changes to reflect your last action.
Cut	This removes selected  text or graphs to a special place called the Clipboard.  This is a temporary holding area.
Copy	This copies selected  text and graphics to a special place called the Clipboard.  This is a temporary holding area.
Paste	This allows you to paste a cut or copied selection as many times as you like, as long as you do not overwrite the contents of the Clipboard by issuing another Cut or Copy command.
Select All	This selects all text and graphic objects in the active window.
Clear	This permanently removes all text and graphics in the active window.
Group	This allows combining multiple text and graphic objects to form a complex image.  You can then work with a single combined object instead of with several individual objects.  You need to select all the text and objects you want to group, then use the Select All command or use the Arrow tool to draw a box around all the objects.
Ungroup	This separates a selected complex image into the individual objects that originally comprised it.
Bring To Front	This allows moving a selected object to be in front of all other objects.
Send To Back	This allows moving a selected object to be in back of all other objects.
