Undo and Redo
You can delete shapes from a document by selecting them and then pressing
the Del or Delete key.
The Delete command from the Edit menu has
the same effect.
Make sure no handles are selected on the shape (the selected handles appear in magenta). Otherwise, you will delete the handles instead of the shape.
Note: You can lock shapes to protect them from deleting. In the Protection floating dialog check the From Deletion option. Then the program will respond with a warning message each time you attempt to delete the shape.
"Undo"
When creating and editing shapes, mistakes are inevitable. So, you may need to cancel a sequence of recent actions and return the document to its previous correct state. The Undo command can be used for this purpose.
To reverse the last action, click the Undo button
on the toolbar, or choose Undo from the Edit
menu. The menu always specifies the type of the action that will be undone.

The number of consecutive actions that can be undone is limited. The default value is 30. You can set the desired value for the active document in the Document Properties dialog (File / Document Properties). The higher the number, the more memory the program requires to store the actions.
"Redo"
The Redo operation is inverse to Undo. Use
it to reverse the latest Undo operation. Click the Redo
button 
on the toolbar, or select Redo
from the Edit menu.
