ShiftRight          <Shift F8>
    -------------------------------------------------------------------------

    Shifts the contents of the currently marked Block (or the cursor
    line, if the cursor does not reside in a marked Block) one position
    to the right.  If you issue this command when the rightmost
    character(s) of the line(s) being shifted is in column 512, that
    character(s) will be deleted to allow the remainder of the line to
    shift right one position.
