 I think a picture says more than 1000 words, here is a screenshot. (I
 hope it will not be blocked). 
Actually, it doesn't.  This screenshot is not dissimilar what you'll get
from using AUCTeX, preview-latex and TeX-fold-mode.
The main "not elsewhere" category I see are XEmacs' extensive input
modes (grid which is sort of a buffer-based menu, keyboard input methods
quite better sorted and convenient than what Quail offers and with
better feedback).  Its buffer reencoding is a rather mixed blessing, but
it works with more than just TeX modes.
