The Keydboard Addsa Character

I have a small Bluetooth keyboard I absolutely love typing on. One problem, of late, it's been adding characters on me, and sometimes getting the order of the letters reversed.

On my proofreads of posts, I often don't catch the typo. The typo isn't the result of my Dysgraphia, but I'm left to wonder if I'm not catching them as a symptom of my Dysgraphia. The disability does include that I can't catch my errors as my mind substitutes the correct form for the error.
