Letter "H" going to end of my sentences when i type

This has been happening the past year or so ,even before the windows 10 upgrade. when I'm typing the letters T and H from the word "the" always goes in front of my cursor and they end up at the end of my sentences. I use a wireless mouse and keyboard and have tried changing them to wired and even buying different brands all with the same result. I've asked in windows forums but have never got a solution to this problem.
