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'
