I haven't quite figured out the details of this, but if text in the rich text applet is the appropriate color of green, it is treated as pass through HTML. I discovered this by creating a table in MS-Word, then cutting and pasting it into the rich text applet. The html appears in one of the greens (though the rich text applet doesn't make it obvious which patch in the color matrix is being used). I also got it to insert a figure into the rich text applet by using the appropriate green on an <IMG SRC=...> code. (Interestingly, the picture itself, not the html code, appears in the rich text applet when it is in edit mode.)
