Re: [ui-dev] Q: How to implement XAccessibleText interface in formula editor ?

[tvraman almaden ibm com]

I'd pretty much go with what Peter said --in addition to introducing a
separate API call that gets the symbolic name --

with respect to the MathML returning API:

You'd like to have the following characteristics:

0) ability to query for the MathML representation of the current
   cursor position (whatever that is:-)-- 

1) the ability to navigate the MathML tree from that position --

 the above is is specific to your question about subscript and
 superscript.
Consider the expression (written using TeX notation which is
 unambiguous  --rather than using ascii graphics--

x+y^\frac{k+1}{2}

when you're on the 'k' that appears in the numerator of the fraction
that is in the superscript, you'd want to be able to traverse the math
logical tree --rather than the 2d layout.
