Other colon symbols are (from math-ext.tex) %D \macros %D {centercolon, colonminus, minuscolon, colonequals, equalscolon, %D colonapprox, approxcolon, colonsim, simcolon, coloncolon, %D coloncolonminus, minuscoloncolon, coloncolonequals, %D equalscoloncolon, coloncolonapprox, approxcoloncolon, %D colonsim, simcoloncolon} %D %D In $a := b$ the colon is not vertically centered with the equal %D to. Also the distance between colon and equal to is a bit large. %D So, we define a vertically centered colon \tex {centercolon} and %D a few macros for colon and double colon relation symbols. %D %D \startlines %D \formula {A \centercolon B} %D \formula {A \colonminus B} %D \formula {A \minuscolon B} %D \formula {A \colonequals B} %D \formula {A \equalscolon B} %D \formula {A \colonapprox B} %D \formula {A \approxcolon B} %D \formula {A \colonsim B} %D \formula {A \simcolon B} %D \formula {A \coloncolon B} %D \formula {A \coloncolonminus B} %D \formula {A \minuscoloncolon B} %D \formula {A \coloncolonequals B} %D \formula {A \equalscoloncolon B} %D \formula {A \coloncolonapprox B} %D \formula {A \approxcoloncolon B} %D \formula {A \colonsim B} %D \formula {A \simcoloncolon B} %D \stoplines The naming is after colonequals.sty rather than mathtools.sty. I find these names easier to remember, but if you want mathtools type names, it is easy to create aliases by \let\coloneqq=\colonequals and so on. Perhaps it is time to create a comprehensive math symbol list for ConTeXt also....
