- unit
- TextRangeUnit
The unit used to move the text range.
- index
-
Int32
int
The index of the specified unit. The text range is relocated to the unit that has this index. If unit is positive, the numbering of units begins at the start of the story and proceeds forward. If negative, the numbering begins at the end of the story and proceeds backward. The start of the story corresponds to index = 1 for all existing units, and the last unit in the story corresponds to index = – 1.
- extend

Boolean
bool
Indicates how to change the text range. True extends the text range to include the unit by moving only the end position of the text range. False collapses the text range to an insertion point and then moves the insertion point. The default value is false.
