Hello *,

Here is a new version of the TeXmacs-maxima interface with enhanced 2D 
mathematical input. It works with the current cvs maxima, and will work 
with maxima-5.9.2 (which will be released soon).

1. Installation
  1.1. bin/tm_maxima goes to /usr/libexec/TeXmacs/bin
       (it replaces an older version)
  1.2. lisp/texmacs-maxima-5.9.2.lisp goes to 
       (this file is new)
  1.3. progs/maxima-input.scm goes to
       (it replaces an older version)

2. How to use
  2.1. Start texmacs
  2.2. Start maxima- with some lisp
  2.3. Click the left icon in the lower row, check Mathematical input

3. What works
  (you can use menus or keyboard equivalents to enter math expressions)
  3.1. Simple things like powers etc.
  3.2. Square roots, n-th roots
  3.3. Greek letters (greek pi means %pi, greek gamma means the Euler 
       constant %ganna, greek capital Gamma means gamma-function);
       to see capital greek letters in the output, you will also need a 
       patch to mactex.lisp which I recently submitted to maxima (not yet 
       in cvs)
  3.4. Satrices, determinants
  3.5. Infinity symbol, emptyset symbol
  3.6. Sums
    3.6.1. Input the big Sum symbol
    3.6.2. As its lower index, input <summation_var> = <lower_bound>
    3.6.3. As its upper index, input <upper_bound>
    3.6.4. After the whole thing, input the summand
           (for a reason unknown, you need to press the right arrow twice 
           to go from the upper limit to the position where you can input 
           the summand)
    3.6.5. In order to show where the summand ends, you need to enter the 
           empty big closing delimiter. I know the following method to do 
           \big <tab> . <enter>
           If there is a simpler way, please, inform me
  3.7. Products - similar to sums
       (unlike sums, pressing the right arroe once brings you from the 
       upper limit to the position where you can type the expression).
  3.8. Indefinite integrals
    3.8.1. Input the big integral sign
    3.8.2. Input the integrand
    3.8.3. Input <blank>, then
           d <tab> <tab> (to produce the differential sign),
           then <blank>, then your integration variable
    3.8.4. \big <tab> . <enter> (to show where the integral ends)
  3.9. Definite integrals - similar to indefinite ones, but after entering 
       the big integral sign you enter the lower and the upper limits as 
       its indices

Best wishes,
