Range Object - Expanding

Expand

Expands the Range or Selection object by a particular unit.

objRange.Expand(Unit:=wdUnits.wdCharacter) 

Unit - The default is wdWord. The unit can only be one of the following constants:

objRange.Expand(Unit:=wdUnits.wdCell) 
objRange.Expand(Unit:=wdUnits.wdCharacter) 
objRange.Expand(Unit:=wdUnits.wdColumn) 
objRange.Expand(Unit:=wdUnits.wdParagraph) 
objRange.Expand(Unit:=wdUnits.wdRow) 
objRange.Expand(Unit:=wdUnits.wdSentence) 
objRange.Expand(Unit:=wdUnits.wdSection) 
objRange.Expand(Unit:=wdUnits.wdStory) 
objRange.Expand(Unit:=wdUnits.wdTable) 
objRange.Expand(Unit:=wdUnits.wdWord) 

Using any other unit will generate a Bad Paramater error.
You can only use wdLine when using a Selection object.

This method returns a value (Long) that indicates the number of characters added to the Range.

objRange.Expand(Unit:=wdUnits.wdCharacter) 

The following expands the Range object to include another sentence
