[NTG-context] question about italic correction

Dear list, I would like to show the difference with italic correction (as well as with expansion and protrusion). I have the following sample: \definefontfeature[default][default][itlc=yes] \definefontfeature[noitlc][default][itlc=no] \setupitaliccorrection[global,always] \starttext {\em of}) \adff[noitlc] {\em of}) \stoptext Is there no way to show italic correction enabled and disabled in the same document? Many thanks for your help, Pablo -- http://www.ousia.tk
