You can use the Calculator to work out the cage combinations for any cage - even one that isn't in the puzzle. Just enter the cage's size (number of cells) and sum. The FILL button (or F key) enters all numbers into the highlighted cells. If fill uses cage combinations is enabled (via the Preferences menu), then it only adds numbers that appear in the respective cage combinations, otherwise it adds all numbers from 1 to 9. If cage combinations are included, the Undo button undoes the last cell change and all changes to cage combinations since the previous cell change. In other words, it (a) undoes all changes to cage combinations since the last cell change, (b) undoes the last cell change, and (c) undoes all changes to cage combinations since the previous cell change. How Am I Doing? If undo includes cage combinations is enabled (via the Preferences menu), then changes to cells (i.e. adding/removing numbers) and cage combinations (i.e. fades in/out) are both undone. Otherwise, only changes to cells are undone.
