We need to find a way to block those keystrokes only in wysiwyg mode. I'm not sure how can we achieve this in a clean way, because blockedKeystroke is mode-blind and undo/redo commands are not even executed at the bottom/top of the stack, because they are disabled then. Our API does not leave us much choice (if any), so new option may need to be proposed." Bug closed Normal CKEditor 4.3.5 General 4.3.2 fixed
