FCAttachTypesettingRule

FCAttachTypesettingRule[expr, ...] attaches a specific TraditionalForm typesetting rule to expr. It doesn’t change any properties of expr apart from adding a FormatValue with a MakeBoxes rule.

Following choices are possible:

• FCAttachTypesettingRule[expr_, str]

• FCAttachTypesettingRules[expr, {SubscriptBox, var, sub}]

• FCAttachTypesettingRules[expr, {SuperscriptBox, var, sup}]

• FCAttachTypesettingRules[expr, {SubsuperscriptBox, var, sub, sup}]

Use FCRemoveTypesettingRules to remove all typesetting rules attached to expr.
