Selections
----------
A selection is a non-empty, directed range with two endpoints called *cursor*
and *anchor*. A selection can be anchored in which case the anchor remains
fixed while only the position of the cursor is adjusted. For non-anchored
selections both endpoints are updated. A singleton selection
covers one character on which both cursor and anchor reside. There always
exists a primary selection which remains visible (i.e. changes to its position
will adjust the viewport).
