(Note: The change caused by this menu option is only 
visible by opening another hypertext file or by using 
a jump link to another file.)

The "Mask Hot Text" menu option sets a 
flag which is used by the OnAssertHotLine  
method of the THyperTextParser component. 
This method is used to override processing of 
hot text detected by the parser. In this case, 
it replaces any text sent to it with asterisks. 
(This could be used to hide secure information
such as social security numbers.)

(Note: Assert methods normally are used to abort
all further processing of an action, while the
Handle Methods modify the processing. These
two methods can each be overridden in code by
direct assignment for Assert types and virtual
overriding for Handle types.)
