Thanks, I solved the problem of potential multiple words and various word terminators by just selecting text the size of each entry. Also "Option Compare Text" is needed to make it case-insensitive.

Option Compare Text
Sub AutoCorrectNow()
Dim orng As Range

For Each Entry In Word.Application.AutoCorrect.Entries
Set orng = Selection.Range
orng.MoveStart wdCharacter, -Len(Entry.Name)
If orng.Text = Entry.Name Then
Entry.Apply orng
Exit For


End If
Next
End Sub
