I don't think eliding words or automatically substituting homophones is a symptom of any disorder, just very common for 'good' typists - good in the sense you don't have to think about the mechanical action of typing or spelling, in the sense you've reducing[1] typing to a sub/unconscious activity.

It's just something occasionally goes wrong with the thought -> word pipeline buffering in the one case. I find the homophone substitution more interesting - I would never, ever make the mistake writing, or if I was paying attention to what I type (I find it happens even more commonly if I'm not paying attention to the window I'm typing on), at some level it seems that the unconscious word-to-keyboard process 'hears' and transcribes somewhat phonetically in a way totally disconnected from my conscious thought process. I find it fascinating I can 'visualize' the spelling of and think a word like, I don't know, 'bare', but my hands, as if completely independent, type out 'bear.'

Another piece is that, if someone talks to me while I am typing, sometimes words from our conversation creep into the text.

Interestingly, I find these mistakes are more common when I am taking stimulants (caffeine) than when I am not.

[1] This is another common mistake I've noticed. I am quite certain I thought 'reduced', but 'reducing' came out anyway. I think this is usually due to me changing the grammatical structure of the sentence midstream; I probably originally thought "you're reducing" instead of "you've reduced", but I typed faster than the thought completed. Maybe this says something about my intellectual capacity. :)

ive noticed all(?) of the things you describe here and i find it interesting to see them put into words like that. Curious that you notice that caffeine has an effect too. Something ive never considered before.

also, i tend to agree with your conclusion, i think what i described are normal human errors, not necessarily signs of dyslexia.

Could well be, but it's amongst a bunch of other things as well.
