Instead of tediously adding new rows and columns and splitting them into words, you may choose to duplicate (clone) your existing grid in any of the four directions (up, down, right or left).
To duplicate the grid, make sure you are in the Edit mode, then select the Edit > Duplicate menu or press the button on the Toolbar. The Duplicate Grid dialog will show up to let you configure how the grid must be duplicated:
Fig. 3.7.2.3.1. Duplicate Grid dialog
Clone down
The duplicated grid will be appended to the bottom.
Let's assume your current crossword looks like this:
Fig. 3.7.2.3.2. Original unmodified grid that will be duplicated
The table below illustrates how the duplication settings (Direction, Mirror and Reverse) affect the structure of the final grid (all examples made without a Border).
Clone Up
Clone Down
Clone Right
Clone Left
No change
(simple cloning)
Mirror
Reverse
Mirror + Reverse
When you've duplicated your grid, you crossword will change its structure. You can proceed to duplicate it again and again, as many times as you want.
Since grid duplication causes the application to reconstruct all words from scratch, all word clues will be lost after each grid modification! This behavior is likely to change in the future, but for now just remember that you will have to rewrite the clues once you're done with grid editing.
