Thank you for the file you put on your site. Indeed everything works

the interaction makes appear the first instance of that formula,
which may be incomplete. Could one have a control over this, that is
for instance, in this particular case, make appear the completed
equation at the end of the slide made with \StartSteps[Navier||Stokes

I'm sorry, I'm no TeX/ConTeXt guru and I really have no idea of how to
achieve this. I think now we need Hans' help.
I have indeed noticed that enclosing an operator between braces breaks
the spacing system. Try, for instance:
\startformula
\vec\nabla\cdot\vec u = 0
\stopformula
\startformula
\vec\nabla\cdot\vec u {=} 0
\stopformula
Unfortunately, using \phatom{=} results in the same broken spacing as
second formula.

We're trying to implement steps-without-JavaScript for slides. You can
get the module here:
http://cfd.homelinux.org/tex/
The current problem, in its simplest form, is that using \mframed breaks
the spacing. Minimal example:
\starttext
We aim to get this spacing:
\startformula
a + b
\stopformula
but when using:
\startformula
a \mframed{+ b}
\stopformula
we get the same broken spacing as in:
\startformula
a {+ b}
\stopformula
\stoptext
> eh ... are you redefining low level macros?
I'd never dare to... ;-) Just overriding \placeformula within
\begingroup/\endgroup to mangle the formula numbers.
Thank you,

Hi Otared,
I can give only explanation but in the moment i do not know the
automatic solution.
Mathematical material are processed in a pieces called atoms. There are
13 different atoms types (ord, op, bin, rel, open, close, punc, ...).
Mathematical characters (+, =, ...) have implicit types (bin, rel; in
the case) or they can be set explicitly (\mathrel{<}, \mathop{\hbox{sin}}).
Spacing in mathematical mode is done according to types of neighbour
atoms. TeX can add
A) no space
B) \mskip\thinmuskip
C) \mskip\medmuskip
D) \mskip\thickmuskip
between atoms if it is surrounded from left or right with
ord op close inner D) REL D) ord op open inner
ord close innerC) BIN C) ord op close inner
PUNCT B) ord op rel open close punct inner
ord close innerB) OPB) ord op
ord op close B) INNER B) ord open punct inner
If no pair is in this table (ord-ord) no space is added.
(Read the table as left-pair and right-pair not as triples.)
Example:
1+1=2
expands like
\mathord{1}\mathbin{+}\mathord{1}\mathrel{=}\mathord{2}
and typeset like
\mathord{1}\C\mathbin{+}\C\mathord{1}\D\mathrel{=}\D\mathord{2}
(abbreviated by \def\B{\mskip\thinmuskip} etc.)
But there are some exceptions (e.g. bin is changed to ord if
nothing bin op rel open punct BIN rel close punct
). It makes things more difficult.
So in your case the math is broken (by steps) into several separates
that is why the atom neighbourhood is lost.
Example. Our 1+1=2 equation can be split to
$1$$+1=2$
and mathbin + changes to ord and we lose space before (beginning of
math) and after (will be ord-ord pair).
In this trivial example it can be solved by
$1$$\mathord{}+1=2$
According to me, mathematical text has to be tuned manually in the
normal case; this spacial one is not a exception ;-(

2) When one refers (see example below) with the command (\in[eq:NS]) to
an equation which has been introduced with \placeformula[eq:NS] the
interaction makes appear the first instance of that formula, which may
be incomplete. Could one have a control over this, that is for instance,
in this particular case, make appear the completed equation at the end
of the slide made with \StartSteps[Navier||Stokes equation]?

[NTG-context] bug with glue and spaces in formulas?
Hi Hans and all Contexters,
While discussing with David Munger about the Steps macros he wrote
for presentations in ConTeXt (see the thread \presentationstep), we
noticed that there seems to be a problem with "white spaces" or glue
around some "binary operators" such as +, - and =.
Please see the result of the following sample.
Best regards: OK
begin file test-glue.tex
\starttext
This is to verify how the space, or glue, is controlled in \ConTeXt.
First some binary operators ``$\in$'', ``$+$'', ``$-$'' and ``$=$''
without grouping braces:
\placeformula[eq:plain]
\startformula
x\in \Omega \subset {\Bbb R}^N,\quad\quad -\Delta u + u -u^3 = f.
\stopformula
Next the same with braces
\placeformula[eq:braces1]
\startformula
x{\in} \Omega {\subset} {\Bbb R}^N,\quad\quad {-}\Delta u {+} u {-u^3} {=} f.
\stopformula
Note how the spaces around the signs $\in$, $+$, $-$ and $=$ have
shrinked. The problem seems to appear when these are actually binary
operators (that is $+1$ and ${+}1$ give the same result, while
$1+2=3$ is different from $1{+}2{=}3$).
I haven't tried all such binary operators, but it seems that this
happens with all of them: compare $A \cap B$ and $A{\cap}B$, or
$A\cup B$ and $A{\cup}B$.
