-### Methods
+### Transforming Methods
 
-#### `getState() => State`
+Since `Selection`s are immutable, all of the transforming methods return a new instance of the selection.
 
-Return the editor's current internal state.
+#### `blur() => Selection`
 
-#### `onChange(state: State) => Void`
+Change the selection's `isFocused` property to `false`.
 
-Effectively the same as `setState`. Invoking this method will update the state of the editor, running it through all of it's plugins, and passing it the parent component, before it cycles back down as the new `state` property of the editor.
+#### `focus() => Selection`
+
+Change the selection's `isFocused` property to `true`.
+
+#### `moveToAnchor() => Selection`
+#### `moveToFocus() => Selection`
+#### `moveToStart() => Selection`
+#### `moveToEnd() => Selection`
+
+Move both of the selection's points to an edge, collapsing it.
+
+#### `moveToStartOf(node: Node) => Selection`
+
+Move both of the selection's points to the start of a `node`.
+
+#### `moveToEndOf(node: Node) => Selection`
+
+Move both of the selection's points to the end of a `node`.
+
+#### `moveToRangeOf(node: Node) => Selection`
+
+Move the selection's anchor point to the start of a `node`, and its focus point to the end of the same `node`.
+
+#### `moveForward(n = 1: Number) => Selection`
+
+Increase the selection's `anchorOffset` and `focusOffset` by `n`, defaulting to `1`.
+
+#### `moveBackward(n = 1: Number) => Selection`
+
+Decrease the selection's `anchorOffset` and `focusOffset` by `n`, defaulting to `1`.
+
+#### `extendForward(n = 1: Number) => Selection`
+
+Increase the selection's `focusOffset` by `n`, default to `1`.
+
+#### `extendBackward(n = 1: Number) => Selection`
+
+Decrease the selection's `focusOffset` by `n`, default to `1`.
+
+#### `extendToStartOf(node: Node) => Selection`
+
+Move the selection's `focusOffset` to the start of a `node`.
+
+#### `extendToEndOf(node: Node) => Selection`
+
+Move the selection's `focusOffset` to the end of a `node`.
