Move Down

  Moves the cursor down one line at a time, as follows:

  o  If the cursor is free, it moves down in the same column.

  o  If the cursor is bound, it moves to the closest corresponding
     position on the next line.  For example, from the end of a line
     longer than the next line, the cursor moves to the end of the next line.

  o  If you are at the end of a buffer, the cursor does not move unless the
     buffer is less than the window length and the cursor is free.

  Command Equivalent:

          GOTO CHARACTER/VERTICALLY/FORWARD
