I want from VBA to start/stop "Track changes" functionality in Excel.

Searching thru the Net I saw a property called `TrackRevisions` of `ActiveDocument` object. Supposedly in MS Word writing `ActiveDocument.TrackRevisions = True` should turn on "Track changes".

But in MS Excel this line gives `424 Object required` run-time error. Same error is returned when trying with `ThisWorkbook`. Changing it to `ActiveSheet` brings `438 Object doesn't support this property or method` error.
