Your "TeXmacs" code snippet


<\eqnarray*>
  1+1=2
</eqnarray*>


is not valid.  There is (or at least should be) no way to produce this kind of invalid content from within TeXmacs.

I have discovered a very useful (undocumented?) feature that transforms equation* into an eqnarray* and backwords.

Eg.

<\eqnarray*>
  <tformat|<table|<row|<cell|1+1>|<cell|=>|<cell|2>>>>
</eqnarray*>

gets converted to

<equation*|1+1=2>

and vice versa.
However if you start with

<\eqnarray*>
  1+1=2
</eqnarray*>

you get

<equation*|>

thus losing all your math.

Also, currently, the code attached to ctrl-& is unnamed so it is (if I understand correctly) impossible to bind it to in a straightforward way to another key.
