Recently, I seem to have been making more than my usual number of typing errors. (I'm a mediocre touch-typer and have been touch-typing for about 45 years.)
The odd thing is that this problem didn't pop up (or at least I didn't notice it) until I had to reload my laptop from scratch several months ago. Since then it seems that I make a fair number of errors, either missed keystrokes or extra ones, never duplicated keystrokes. Sometimes it seems like a spell-checker run amok, since I'll type "the" and it will come out "then", or vice-versa, but it happens on Stack Exchange sites as often as it happens in, say, MS Word.
It's probably all in my doddering head, but I thought (hoped?) that there was the odd chance that someone had an explanation that wouldn't simply point me towards The Home a few years before I'm ready.
