//	Style handling:

- applyToSimilar: (HTStyle *)style;	// Apply this style to the selection
- applyStyle: (HTStyle *)style;		// Apply this style to the selection
- selectUnstyled: (HTStyleSheet *)sheet;// Select the first unstyled run.

//	"Fast" Methods for external parsers:

- appendBegin;				// Start an append sequence
- appendStyle:(HTStyle *) style;	// Set the style for future text
- appendText: (const char *)text;	// Add a string
- appendCharacter: (char)ch;	// Add a string
- appendBeginAnchor: (HTAnchor *)a;	// Begin an anchor
- appendEndAnchor;			// End it
- appendEnd;				// Flush out all additions so far


//	Anchor handling:


//- anchors;				// Set of anchors
- nodeAnchor;				// Single anchor representing this node
- followLink;				// (If selected)
- unlinkSelection;			// Remove anchor info from selection
- (Anchor *) referenceSelected;		// Generate anchor for this node
- (Anchor *) referenceAll;
- (Anchor *) linkSelTo: (Anchor*)anchor;// Link selected text to this anchor.
- disconnectAnchor: (Anchor*)anchor;	// Remove reference from this node.
- selectAnchor: (Anchor*)anchor;	// Bring to front and highlight it.

- setTitle:(char *)title;
- dump: sender;			// diagnostic output

//	Override methods of superclasses:

- readText: (NXStream *)stream;		// Also set format variable.
- readRichText: (NXStream *)stream;	// Also set format variable.
- mouseDown:(NXEvent*)theEvent;		// Double click become hyperjump
- keyDown:(NXEvent*)theEvent;		//
- paste:sender;				//

//	Window delegate methods:
