# Extra vertical space between aligned equations in ConTeXt?

In LaTeX, I can use \\[3mm] for example, to put extra vertical space, if I think it will improve the readability of displayed, aligned equations. And in fact I find I do this quite a bit. But what is the ConTeXt equivalent to this?

ConTeXt does not have an interface for increasing the interline space. You would have to add the space manually. For example:

\startformula \startalign
\NC a \EQ b + c \NR
\noalign{\blank[2cm]}
\NC a \EQ b + c \NR
\stopalign \stopformula


If you want, you can add an interface for it. I did not test it too thoroughly.

\unprotected\def\doalignNR[#1][#2]%
{\donestedformulanumber{#1}{#2}\crcr
\noalign{\mathalignmentparameter\c!inbetween}}


Then you can use:

\definemathalignment[loosealign][inbetween={\blank[2cm]}]

\starttext

\startformula \startloosealign
\NC a \EQ b + c \NR
\NC a \EQ b + c \NR
\stoploosealign \stopformula

Thank you very much: the \noalign{\blank[2cm]} does exactly what I want. –  Alasdair Feb 28 '11 at 9:28
