Install an Element

New element(s) can be installed in the edited sequence by the commands

object-name:class-name,AT=at-expression,SELECTED,attributes;
object-name:class-name,AT=at-expression,FROM=place,attributes;
object-name:class-name,AT=at-expression,attributes;
class-name,AT=at-expression,SELECTED;
class-name,AT=at-expression,FROM=place;
class-name,AT=at-expression;

It has the following attributes:

object_name

The name of the element to be installed. If the object name is given, attributes may also be specified to override the attributes of the class.

class_name

The name of the class from which the element is to be defined.

AT

The position where to install the element.

FROM

Three cases are possible:

SELECTED

New elements are inserted at AT=at-expression from each currently selected element.

FROM=place

A new element is installed at position AT=at-expression relative to the (unique) element at place.

FROM omitted or blank

A new element is installed at the absolute position AT=at-expression.

Relative positions may be negative.

The two names object-name and class-name interact in the same way as for a sequence definition. The reference points for elements is defined by the REFER attribute of the SEQUENCE.
