Have noticed this strange spoonerism while typing. I?ve noticed that some fingers of mine are much faster than others, leading to common mis-spelling. I often type ?dinfing? instead of ?finding? and I don?t even count the number of times I type ?teh? for ?the?. and “gatline” for “tagline”. interestingly a lot of such mistakes happen when my left index ginfer is involved!
Another common mistake I make while typing is using the wrong hand. On a number of occasions I type S (left ring finger) instead of L (right ring finger) and vice versa. Similarly I keep interchanging E and I!
