The "\definebar[...][inlined]" doesn't look quite right though -- the
issue that I'm having is that I can't figure out how to highlight across
both sides of an \alignhere without any questionable hacks. Unless the
new "inlined" does work across an \alignhere and I'm just not seeing it
in the example.
Thanks again,

I can confirm that it works over \alignhere. Hans is doing some black
magic, but I guess he did not want to show off by including the whole
line.
Indeed, no need to show of the obvious
\definebar
[mybar]
[backgroundbar]
[height=\strutht,depth=\strutdp,offset=.250ex,color=red]
\definebar
[yourbar]
[backgroundbar]
[height=\strutht,depth=\strutdp,offset=.125ex,color=blue]
\definebar
[ourbar]
[backgroundbar]
[height=\strutht,depth=\strutdp,offset=.125ex,color=green]
\starttext
\startTEXpage[width=4cm]
\startformula
a \alignhere= b + c \breakhere
\mybar {d + \yourbar{e \alignhere=} f \breakhere
g \alignhere \ourbar{=} h} + i
\stopformula
\stopTEXpage
\stoptext
Especially when it would not pass the rigourous accessibility check (esp
wrt color) of your university,
Hans

maybe
\starttexdefinition protected newintertext #1
\leftparbox [global] {
\vadjust pre \bgroup
\forgetall
\vskip.5\strutdp % needs to be more clever in the end
\dontleavehmode\vtop\bgroup
#1
\egroup
\egroup
}
\breakhere
\stoptexdefinition
but i need to discuss it with Mikael as we might integrate something
better and then it needs to be documented (in the upcoming manual) as well

[NTG-context] \intertext and highlighting with \alignhere/\breakhere
Hi all,
Often I want to include a sentence/paragraph in the middle of a long
multipart formula. With the old \startalign/\stopalign formulas, I could
use \intertext{...} to do this, but this doesn't work with the new
\alignhere/\breakhere formulas. I've managed to find a "solution" for
this, although I'd prefer something a bit less hacky. Any ideas?
Also, is there a way to highlight an equation across an \alignhere? Once
again, I've found a "solution", but like before, it's pretty hacky.
