MS Word can toggle hidden text off/on almost instantaneously, even in 
huge files with thousands of instances of hidden words. This indicates 
that it is not using a process of iteration, but is toggling some global 
feature.

The feature must be part of the WinAPI RichEdit control, not the MS 
Office engine, since the DevExpress XtraRichEdit control also has this 
capability, and it doesn't require the presence of MS Office.

I'm looking through the rtf specification to see if I can find anything.
