Description

Define a font feature set as a collection of OTF font features turned on or off. A font feature set can be activated with \setff or \addff. To modify an existing font feature set, use \definefontfeature; that way, the OTF features you (in)activate are added to the ones already in the set.

Example

Add onum=yes to the default feature set:

• \definefontfeature[default][default][onum=yes]
  
  \setupbodyfont[schola,8pt]
  
  \starttext
  \startTEXpage[offset=2.5em]
  1234567890
  \stopTEXpage
  \stoptext
  

• 

Make a new feature set that sets onum=yes, and activate it next to the active set with \addff:

• \setupbodyfont[schola,8pt]
  
  \definefontfeature[oldstyle][onum=yes]
  
  \starttext
  
  \startTEXpage[offset=2.5em]
  1234567890 {\addff{oldstyle}1234567890}
  \stopTEXpage
  \stoptext
  \stoptext
