== Using double stroke the doublestroke font ==

Computer Modern and Latin Modern use the msbm font family for [[Blackboard bold|blackboard bold]]. msbm look very dull and usually black board bold should be avoided in math. However, there are certain cases where one needs something ''fancier'' than math bold. The [http://ctan.org/tex-archive/fonts/doublestroke doublestroke fonts] offer one such alternative. This is how these can be used with ConTeXtFor an example of what it looks like, see [http://mirrors.ctan. Note that since we are using org/fonts/doublestroke fonts as the blackboard font, there is really no need to use the blackboard fonts separately/dsdoc. So, the mb math family is reusedpdf its documentation].
