Macro to insert comments on keywords in selected text in a Word doc? - vba

Question

I'm new to VBA and would greatly appreciate some help on a problem.
I have long Word documents where I need to apply standard comments to the same set of keywords, but only in selected sections of the document. The following macro worked to find a keyword and apply a comment (from question here https://superuser.com/questions/547710/macro-to-insert-comment-bubbles-in-microsoft-word):
Sub label_items()
'
' label_items Macro
'
'
Do While Selection.Find.Execute("keyword1") = True
ActiveDocument.Comments.Add range:=Selection.range, Text:="comment for keyword 1"
Loop
End Sub
The two modifications are:
1) only apply the comments to user selected text, not the whole document. I tried a "With Selection.Range.Find" approach but I don't think comments can be added this way (??)
2) repeat this for 20+ keywords in the selected text. The keywords aren't totally standard and have names like P_1HAI10, P_1HAI20, P_2HAI60, P_HFS10, etc.
EDIT: I have tried to combine code from similar questions ( Word VBA: finding a set of words and inserting predefined comments and Word macro, storing the current selection (VBA)) but my current attempt (below) only runs for the first keyword and comment and runs over the entire document, not just the text I have highlighted/selected.
Sub label_items()
'
' label_items Macro
'
Dim selbkup As range
Set selbkup = ActiveDocument.range(Selection.range.Start, Selection.range.End)
Set range = selbkup
Do While range.Find.Execute("keyword 1") = True
ActiveDocument.Comments.Add range, "comment for keyword 1"
Loop
Set range = selbkup
Do While range.Find.Execute("keyword 2") = True
ActiveDocument.Comments.Add range, "comment for keyword 2"
Loop
'I would repeat this process for all of my keywords
End Sub
I've combed through previous questions and the Office Dev Center and am stuck. Any help/guidance is greatly appreciated!

It's a matter of adding a loop and a means of Finding the next keyword you're looking for. There are a few suggestions in the code example below, so please adjust it as necessary to fit your requirements.
Option Explicit
Sub label_items()
Dim myDoc As Document
Dim targetRange As Range
Set myDoc = ActiveDocument
Set targetRange = Selection.Range
'--- drop a bookmark to return the cursor to it's original location
Const RETURN_BM = "OrigCursorLoc"
myDoc.Bookmarks.Add Name:=RETURN_BM, Range:=Selection.Range
'--- if nothing is selected, then search the whole document
If Selection.Start = Selection.End Then
Selection.Start = 0
targetRange.Start = 0
targetRange.End = myDoc.Range.End
End If
'--- build list of keywords to search
Dim keywords() As String
keywords = Split("SMS,HTTP,SMTP", ",", , vbTextCompare)
'--- search for all keywords within the user selected range
Dim i As Long
For i = 0 To UBound(keywords)
'--- set the cursor back to the beginning of the
' originally selected range
Selection.GoTo What:=wdGoToBookmark, Name:=RETURN_BM
Do
With Selection.Find
.Forward = True
.Wrap = wdFindStop
.Text = keywords(i)
.Execute
If .Found Then
If (Selection.Start < targetRange.End) Then
Selection.Comments.Add Selection.Range, _
Text:="Found the " & keywords(i) & " keyword"
Else
Exit Do
End If
Else
Exit Do
End If
End With
Loop
Next i
'--- set the cursor back to the beginning of the
' originally selected range
Selection.GoTo What:=wdGoToBookmark, Name:=RETURN_BM
End Sub
