I was working on a Word document and a window came up offering a feature
which slows down the typing and helps prevent redundant keystrokes. I meant
to cancel the feature but activated it instead. It is so annoying. It is
difficult to repeat keystrokes (like in the word "difficult"). How can I turn
this feature off?
