\showbodyfont : actual bodyfont family with all variants

  • \showbodyfont[pagella,7pt]

\showbodyfontenvironment : draws a table that shows which point sizes match the relative sizes

  • \showbodyfontenvironment[pagella,7pt]

\showsymbolset[symbolset name] : shows all the symbols within a given symbol set

  • \showsymbolset[navigation 1]

\ShowCompleteFont and \showmathcharacters

\ShowCompleteFont from module fnt-10 : list of available chars of actual bodyfont encoding (for MkII, \showcharacters lists the available chars of actual bodyfont encoding ) 

  • \usemodule[fnt-10]
\setupcolors[state=start]
\starttext
\ShowCompleteFont{name:texgyrepagella}{8pt}{1}
\stoptext

Then you can use \utfchar and/or \fontchar: 

  • \definedfont[name:modern*default at 50pt]
\utfchar{0x02660} or
\utfchar{"02660} or
\utfchar{"2660} or
\fontchar{spade}

\showmathcharacters from module math-characters : list of all the available math (non-alphabetical) characters available in math, now including all the AMS characters. 

  • \usemodule[math-characters]
\setupcolors[state=start]
\setupbodyfont[pagella,7pt]
\starttext
\showmathfontcharacters
\stoptext

\showstruts : display struts (invisible placeholders for proper minimum line heights)

(Make a better, slightly more complex example.) 

  • \setupbodyfont[pagella,7pt]
\framed[frame=off,align=normal]{\showstruts
This will display \strut struts.\crlf
A frame with strut \framed[strut=yes]{xxx} and frame without \framed[strut=no]{xxx}}

\showfontstrip : the current typeface combination, with roman, sans, math, and teletype families visualised, with x-heights and m widths.

  • \setupbodyfont[pagella,7pt]
\framed[frame=off]{\showfontstrip}

\tracedfontname{Font Name} : Chain of synonyms for the given font name

  • \setupbodyfont[pagella,7pt]
