When modifying text it is not necessary to select the text before modifying it

activedocument.content.paragraphformat.space 2 

Dim objParagraph As Paragraph 
Set objParagraph = ActiveDocument.Paragraphs(2) 
objParagraph.Alignment = wdParagraphAlignment.wdAlignParagraphLeft 

Dim objRange As Range 
Set objRange = ActiveDocument.Paragraphs(2).Range 
objRange.Font.Bold = True | False 

Dim objFont As Font 
Set objFont = ActiveDocument.Paragraphs(2).Range.Font 
objFont.Bold = True | False 

objDocument.EmbedTrueTypeFonts = 

These two lines are equivalent

objDocument.Paragraphs(2).CloseUp 
objDocument.Paragraphs(2).SpaceBefore = 0 

objDocument.Paragraphs(2).SpaceAfter = 0 

Dim objParagraphFormat 
objParagraphFormat = objParagraph.Format 

The Range property returns a Range object that represents the portion of a document that is contained in the paragraph

objRange = objParagraph.Range 
objRange.Text = "some text" 
objRange.Font.Name = "Arial" 

All the properties and methods of the ParagraphFormat object are also properties and methods of the Paragraph object except the Duplicate property.

Manipulates the currently selected paragraph

With Selection.Paragraphs(1).Range 
   .Font.Bold = False 
End With 

Get the Index number of the current paragraph

Define a range from the start of the document to the end of the first selected paragraph

Msgbox (ActiveDocument.Range(0,Selection.Paragraphs(1).Range.End).Paragraphs.Count) 

Determine if the selection is at the start of a paragraph

For ranges substitute the range for the selection.

If Selection.Start = Selection.Paragraphs(1).Range.Start Then 

End if 

Selection.Sections(1) or Selection.Tables(1)

Selection.ParagraphFormat.Alignment = wdAlignParagraphCenter 

Selection.ParagraphFormat.LeftIndent = InchesToPoints(2) 
Selection.ParagraphFormat.RightIndent = InchesToPoints(2)
