I have found those issues as well, sometimes. I try not get frustrated. I close my eyes, take a breath and be calm. When I’m worked up nothing runs smoothly. I realize I’m not going to set any records in The Guinness Book Of Records for speed typing, so I just take my time typing. I’ve also found typing on my iPad, with the touch screen keyboard, a little easier and less fatiguing. But that could just be me.
