Hi ACA,
You could possibly use a macro like the following. It goes though all sentences in the document, asking for you to translate them. If you edit or leave a given sentence alone, the next sentence is selected. Pressing cancel exits the macro.
Code:
Sub Translation_Assistant()
Dim Rng As Range, Rslt
With ActiveDocument
For Each Rng In .Sentences
With Rng
.MoveEndWhile Cset:=" ", Count:=wdBackward
.End = .End - 1
.Select
If .Style <> "Trans" Then
Rslt = InputBox("Please translate this sentence.", "Sentence translation", .Text)
If Rslt = vbNullString Then Exit Sub
.Text = Rslt
.Style = "Trans"
End If
End With
Next
End With
End Sub
The code assumes the existence of a Character Style (which you can easily create) named 'Trans'. This doesn't need any special attribute, though you could give it a font colour, for example. This Style is applied to each sentence as it's translated/skipped. Any sentences already having that Style will be skipped next time you run the macro.
