I just tried the same and had a very hard time typing gti. I had to slow down to get it; if I try to type it as quickly as possible I end up with either "git" or "gir". The parallization between hands just makes it too easy to type correctly. While your left pointer finger is making that long move from g to t, your right middle finger is already done pressing i.
When you use the same finger to type the G and T and a different finger to type I, it seems really impossible for me to accidentally type G-T-I.
The more common mistake is when you have to type two consecutive letters with the same finger but end up typing the next one earlier because its on a different finger (usually on the opposing hand).
Ex: 'teh' instead of 'the'- T,H with left index finger. E with left middle finger.
I also almost never type 'sl' though I do often type 'qw' in the Vim command line instead of 'wq'
Thanks for telling me that! I realized that I can make the same mistakes locally with comparable frequency. Perhaps it's just that I feel annoyed when I have to backspace with latency.
It predicts what the server will do with your input and displays the result (with an underline) until the server responds. This means typing is always at local speed even if the network is being flaky.
I never type "sl" either.
