A small number of lines
can be kept as history.  Using ^P (and ^N), the current line can be replaced
by any one of the previously typed lines.</P

command, additional editing commands are possible. 
As data are entered for this command, the current/previous value
will be displayed and the cursor placed at the end of that data.
The user may use the editing keys (above) to move around in the data
to modify it as appropriate.
Additionally, when certain
characters are entered at the end of the current value, 
i.e. entered separately, certain behavior is elicited.</P

pressing ^ when changing item B, allows you to change item A. This is similar
to the up arrow.
Note: ^P and ^N do not have the same meaning while editing 
<B
