Championed by Gold Trowel, although I’m sure they wouldn’t of invented it, the typewriter method is when for example you start at the top left of a wall, cover the the top half/third towards the right side of the wall, then start back at the left, laying on the bottom/middle etc. It is just a more structured technique for laying the plaster on. Of course it goes the same for ceilings, start at one corner, complete a ‘line’ then start back at the same side you began.
