Public Function MoveUp (unit As TextRangeUnit, count As Integer, extend As Boolean) As Integer

Parameters

unit: TextRangeUnit

The units by which to move the insertion point or active end. The following values are valid.

Value	Corresponding key combination	Meaning
Line	Up Arrow	Moves up one line. This is the default.
Paragraph	Ctrl+Up Arrow	Moves up one paragraph.

count: Int32
int

The number of units to move. The default value is 1.

extend: Boolean
