Sorry, Some KB's seem to have a parental nanny control that censors what it deems to be inappropriate in the text. SK won't allow 4 letter words which can be appropriate at times for certain emphasis. I hadn't used it in awhile because it had some issues with double lettering and double words. So, giving it another try on my 10 and it censors words I write. The "F" word typically is swapped out for "CHECK. If I try to delete and force it, it won't let me and goes back to swapping in "CHECK". There used to be a setting (I thought) that allowed any words. Hence the nanny control.
