6.2 Generic Sexp Widget

The sexp widget can contain any Lisp expression, and allows the user to edit it inline in the buffer.

The syntax for the sexp widget is:

type ::= (sexp [keyword argument]...  [ value ])

Widget: sexp

This will allow you to edit any valid s-expression in an editable buffer field.

The sexp widget takes the same keyword arguments as the editable-field widget. See editable-field.
