Inherited functions

From class BaseMovementMethod

`Int`	`getMovementMetaState(buffer: Spannable!, event: KeyEvent!)` Gets the meta state used for movement using the modifiers tracked by the text buffer as well as those present in the key event. The movement meta state excludes the state of locked modifiers or the SHIFT key since they are not used by movement actions (but they may be used for selection).
`Boolean`	`onGenericMotionEvent(widget: TextView!, text: Spannable!, event: MotionEvent!)`
`Boolean`	`onKeyDown(widget: TextView!, text: Spannable!, keyCode: Int, event: KeyEvent!)`
`Boolean`	`onKeyOther(widget: TextView!, text: Spannable!, event: KeyEvent!)`
`Boolean`	`onKeyUp(widget: TextView!, text: Spannable!, keyCode: Int, event: KeyEvent!)`
`Boolean`	`onTrackballEvent(widget: TextView!, text: Spannable!, event: MotionEvent!)`
