* a complete font change ({{cmd|setupbodyfont}}, {{cmd|switchtobodyfont}}).
== Warnings Before you start ... ==
1. Placing a font switch at the begin of a paragraph can sometimes generate unexpected side-effects. This can be avoided by forcing horizontal mode before any font change:
{{cmd|em}} switches to slanted; and if the current font alternative is slanted,
{{cmd|em}} switches to normal.

As defined in [[source:font-ini.mkivmkvi|font-ini]]. All sizes in pt, except factor.
\c!em=\v!slanted]
</texcode>
'''N.B.''': <code>scirpt</code> and <code>scriptsize</code> are used in math mode.
It is also possible to set the scaling factors for specific font sizes. For example, if you want {{cmd|tfa}} to set the effective font size to 12pt when the bodyfont size is 10pt, and to set the effective font size to
14pt when the bodyfont size is 11pt, then add
<texcode>
\definebodyfontenvironment [11pt] [a=14pt]
</texcode>
'''Note:''' When the first parameter is <code>default</code>, the scaling factors ''must'' have numerical values. When the first parameter is a font size (e.g., <code>12pt</code>), the scaling factors can either be numerical value or a dimension.
{{cmd|definebodyfontenvironment}} is described in detail in
the ConTeXt manual and the [[source:font-ini.mkiv|font-ini]] source file.
In addition, the commands {{cmd|smallbodyfont}} and
{{cmd|bigbodyfont}} can be used to change the font size. The relative size depends on the value of <code>big</code> and <code>small</code> in {{cmd|definebodyfontenvironment}}.
These mnemonic font switches are pretty smart. You can either use them as
\setuphead[section][style=bold]
</texcode>
(<code>\boldface</code> shown above is also defined to parallel the
<code>\typeface</code> and <code>\swapface</code> switches.)
== Capitalizing words ==
* Note that {{cmd|WORD}}, {{cmd|Word}} and all following macros aren't ''switches'', but ''commands'' (brackets behind, not around): <tt>{</tt>{{cmd|em}} <tt>switch}</tt>, vs {{cmd|Word}}<tt>{macro}</tt>.
== Underline, strike through, and overline ==
* Underlined, struck, and overlined text can be achieved with {{cmd|overbar}} , {{cmd|overbars}}, {{cmd|overstrike}}, {{cmd|overstrikes}}, {{cmd|underbar}}, and {{cmd|underbars}}.
The canonical way is <code>\overstrike{text}</code>. However, it you're using mycrotypography with <code>\setupalign[hz,hanging]</code> expect the rule to be placed over the character (with the Latin Modern fonts you should not have this problem, experienced with Linux Libertine and mkiv). This is not what is expected. The workaround is to put the overstriked text in a <code>\inframed[frame=off]{}</code>.
E.g.
<texcode>
bla bla bla \inframed[frame=off]{\overstrike{striked}} bla bla
</texcode>
<context>
bla bla bla \inframed[frame=off]{\overstrike{striked}} bla bla
</context>
Disabling mycrotypography also works, but probably not desiderable.
