Selection class
A object represents the range of text selected by the user or
the current position of the caret. To obtain a object for
examination or manipulation, call window.getSelection().
A user may make a selection from left to right (in document
order) or right to left (reverse of document order). The anchor
is where the user began the selection and the focus is where the
user ends the selection. If you make a selection with a desktop
mouse, the anchor is placed where you pressed the mouse button,
and the focus is placed where you released the mouse button.
Note: Anchor and focus should not be confused with the start and end positions of a selection. The anchor can be placed before the focus or vice-versa, depending on the direction you made your selection.
