coordinates. If the index is invalid an empty rectangle is
returned. |

}
} Given a point in local coordinates, return the zero-based index
of the character under that Point. If the point is invalid,
this method returns -1. |

} Returns the start offset within the selected text.
If there is no selection, but there is
a caret, the start and end offsets will be the same. |
