To use a macro to accomplish this, you have to check each paragraph in your document and check to see if it is a "Header" style. If so, then pick off the value of the first tab stop to set as the indent for the subsequent paragraphs.
UPDATE1: the earlier version of the code below set the paragraphs to the Document
level first tab stop, and did not accurately grab the tabstop set for the Heading
styles. The code update below accurately determines each Heading
indent tab stop.
UPDATE2: the sample text original I used in shown in this first document:
The code that automatically performs a first line indent to the tab level of the preceding heading is the original Sub
from the first example:
Option Explicit
Sub SetParaIndents1()
Dim myDoc As Document
Set myDoc = ActiveDocument
Dim para As Paragraph
Dim firstIndent As Double 'value in "points"
For Each para In myDoc.Paragraphs
If para.Style Like "Heading*" Then
firstIndent = myDoc.Styles(para.Style).ParagraphFormat.LeftIndent
Debug.Print para.Style & " first tab stop at " & _
firstIndent & " points"
Else
Debug.Print "paragraph first line indent set from " & _
para.FirstLineIndent & " to " & _
firstIndent
para.FirstLineIndent = firstIndent
End If
Next para
'--- needed to show the changes just made
Application.ScreenRefresh
End Sub
And the results looks like this (red lines added manually to show alignment):
If you want the entire paragraph indented in alignment with the heading style, the code is modified to this:
Option Explicit
Sub SetParaIndents2()
Dim myDoc As Document
Set myDoc = ActiveDocument
Dim para As Paragraph
For Each para In myDoc.Paragraphs
If para.Style Like "Heading*" Then
'--- do nothing
Else
para.Indent
End If
Next para
'--- needed to show the changes just made
Application.ScreenRefresh
End Sub
And the resulting text looks like this:
