latex-mode is has a nice display of superscripts and subscripts. Not
only are they reduced in size, but they are respectively raised and
lowered a bit relative to the current line.
Q: How can I make part of the text in a line look like a superscript?
I know how to make text small (with the
heightface property), but I
don't know how to raise it. I tried to investigate
all I could find was that
font-latex-superscript-face had a small
height property (which doesn't account for the raising).
