The only thing which the Rich Edit Control and MS Word (and others like
e.g. WordPad) have in common is that they use the Text Object Model (TOM).
MS Word does _not_ make use of the Rich Edit Control! The Rich Edit
Control, MS Word and presumably also the "DevExpress XtraRichEdit" are
administrating the data with the TOM but each one of these has its own
method to render the data to a certain device like the screen. The
rendering is the point at which a "global toggle" for hidden text is to be
implemented. And while MS Word implements such a "global toggle" the Rich
Edit Control AFAIK does _not_. If you want to implement a "global toggle"
for hidden text you have to implement your own rendering method.
