Remedy For 'volatile' Insertion Point With Text Writing?

Has anyone encountered a text-writing issue where one is engrossed in what is being typed without realizing that the insertion point has jumped from sequence--i.e., the latter part of a word currently being typed has located itself after a term on a prior line (the issue always entails a 'jump' back to prior written text)?

I've observed it occurring--the insertion point just reverts/jumps to a prior line--and not always at the beginning of a line, either.

Q: is it feasible that the keyboard has a (for lack of a better term) 'sensitivity' control, to make the keyboard less hyper?
