editing of lines in the terminal version

Summary:

The line editor is only available in the terminal version of MuPAD, not under
the X-Window-System  or on the Macintosh.

The current text line can be edited with the line editor during interactive
input.  The commands of the line editor are entered as control characters
through simultaneous pressing of the control key and a second one, e.g.
<Ctrl-A> indicates the simultaneous pressing of the control and A keys. The
available commands are:

<Ctrl-A>         cursor to line beginning.
<Ctrl-Y>         cursor to the beginning of the previous word.
<Ctrl-B>         cursor one character to the left.
<Ctrl-F>         cursor one character to the right.
<Ctrl-Z>         cursor to the beginning of the next word.
<Ctrl-E>         cursor to the line end.
<Ctrl-U>         delete the complete input line.
<Ctrl-W>         delete from the cursor position to the beginning of the previous
                 word.
<Ctrl-H>         delete the character left of cursor.
<Ctrl-D>         delete the character under the cursor.
<Ctrl-T>         delete the next word.
<Ctrl-K>         delete to end of line.

 <Ctrl-L>         insert the last input line before the current cursor position.
 <Ctrl-P>         reproduction of the last input line. Repeated pressing of <Ctrl-P>
                  successively reproduces the previous input line. If the cursor is not
                  at the beginning of the line then the previous lines are searched for

                  an entry that corresponds to the characters of the current input.
 <Ctrl-N>         analogue to <Ctrl-P>, but the previous input is run through in
                  reverse order.
