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.

Is your keyboard clean? I once had a dust problem that caused certain simultaneous presses to fire other keys. I think the dust was as an electrical conductor. – Louis Dec 15 '12 at 2:20
Have you tried using another keyboard or another computer to see if you get the same results? – qw3n Dec 15 '12 at 2:22
@qw3n - It's a laptop, so I'm pretty well stuck with this keyboard. (I could use a USB keyboard, I suppose, but it would be pretty artificial, and the errors aren't quite frequent enough to make for a reliable experiment.) – Daniel R Hicks Dec 15 '12 at 3:11
@Louis - Keyboard is fairly clean. I guess I could work it over with Ciber Clean, though. – Daniel R Hicks Dec 15 '12 at 3:12
