Sort by Order Num

The button Sort by Order Num can be used to rearrange the definition lines. If for whatever reasons you will rearrange the lines, just define the numbering in an ascending order and press the Order button afterwards. Lepg will reorder the lines according to the numbering you’ve choosen.
