Hi there
A very common method of solving a sudoku starts with filling the pencilmarks 1 through 9 in all empty cells and then clearing the inadequate possibilities according the sudoku rules. This procedure is rather annoying and time consuming. Does there exist a shortcut for this part of the work, e.g. by copying all the pencilmarks of a cell and pasting them to other cells?
I created a little Excel-table that does the job, but copying the numbers from the Excel sheet to the sudoku program by hand lasts almost as long as if I do it in the way outlined above.
Thanks for a hint
