not a typo

I just caught an error in an email I was bout to send out - I'd intended to type that an idea I was working on was based "very loosely" on an idea I'd worked on previously. Yet what I typed was "very closely" - if you check your keyboard, you'll see that's no regular typo, as the c key is far from the other keys used in the sequence eryclo. This was a full-on lexical access error (and antonymic to boot). Wondering if anyone had studied this, I looked up LLBA with search terms {lexical and {retrieval or access} and typing}, but none of the hits pertain to my question. Meanwhile, I'm wondering how much of what I've written in the last 20 years on keyboards has included similar errors.
