// this is a HACK. If the data source browser is opened in the "beamer", while the main frame
// contains a writer document, then pressing enter in the DSB would be rerouted to the writer
// document if we would not do this hack here.
// The problem is that the Writer uses RETURN as _accelerator_ (which is quite weird itself),
// so the SFX framework is _obligated_ to pass it to the Writer if nobody else handled it. There
// is no chance to distinguish between
// "accelerators which are to be executed if the main document has the focus"
// and
// "accelerators which are always to be executed"
//
// Thus we cannot prevent the handling of this key in the writer without declaring the key event
// as "handled" herein.
//
// The bad thing about this approach is that it does not scale. Every other accelerator which
// is used by the document will raise a similar bug once somebody discovers it.
// If this is the case, we should discuss a real solution with the framework (SFX) and the
// applications.
