Aside from being an excellently cromulent word, ‘machigne’ is what I often type when attempting to type ‘machine’. It seems to be because the ‘g’ allows for all of the transitions between letters to go from left hand to right hand and back:

machine: l,r,l,r,l,l,r*
machigne: l,r,l,r,l,r,l,r

*Note that this was really difficult to type, as it involved using one of the weakest fingers for two consecutive characters (‘l’, ‘,’).
