I think it works using statistical probability for letter pairs &
triplets.

My in-car Sat Nav system uses rotary selection of letters (dial the
letter you want), eliminating letters which are not relevant as the
choice is narrowed down. This works surprisingly well, despite the
cumbersome description!

In addition to differentiating direction of travel, rotary selection
can also react to speed of rotation. With a bit of ingenuity, it's
possible to design UI's which are (IMO...) far more elegant and
intuitive than a push button interface - not only that, but it's
economic on the input bits too.

If we are going to have push button inputs, aligning them parallel to
screen edge will also give the option of a "soft key" style UI,
without compromising cursor-style navigation.
