I am right handed. I always fancied myself to be at least hintingly ambidextrous as a [very young] child, but I never really pursued it beyond writing left-handed occasionally. I’ve decided to be left-handed for a while, see how that goes. Hopefully it’ll be interesting.
The first problem I’ve hit, apart from being pretty spastic left-handed, is that there’s no Control key on the right-hand side of the keyboard, so I can’t just mirror my normal trackpad mousing.
It’s also difficult to fight the habit of reaching for the trackpad or mouse with my right hand.
