I notice that the autocorrect in Lion uses the character positions in order to suggest which correction to be made:
For example, if I type thst really fast, it will correct it to that but if I type thet, it corrects it to they.
This makes sense on a Qwerty keyboard, since the s is by the a, and the t is next to the y. However, it wouldn't make much sense on a different layout such as Dvorak.
Does Mac OS X Lion take into account which keyboard layout you are using and offer suggestions based on keys that are nearby the typo?
What if I created an entirely new keyboard layout, and use that instead of a keyboard layout which comes with Lion?
