In math mode, I hit \frac, Texmacs will give me the denominator and
numerator to fill. Is there a way to tell whether the cursor is at the
denominator or numerator using Scheme code?
If one can, then it is possible to write in Scheme code a shortcut to
to jump from numerator, then to denominator, then out of the whole
fraction. It would be nice to have such a shortcut.
