Hi,

as a minor improvment you might want to alter those functions to select
the next entry that is the next graphically adjacent element, instead of
just the next element in the list.

Currently this makes moveNext spiral outwards from the center, but I
think this is dependent on the way td_elementmap is constructed, i.e. an
implementation detail.

(If this is the intended behavior, it should be documented in
movePrev/moveNext's, and possibly where td_elementmap is constructed.)

Cheers,
Daniel
