Undo Function Key 

The Undo function key is available while you are editing in visual mode.
It will Undo the modifications which were caused by pressing Return or a
function key.

When the Undo key is pressed, your screen is repainted.  The Undo buffer
will be reset when another edit modification key is pressed or a new
screen is transmitted.

Example
