Horizontal addition looks inside productions: it adds any marked part of an internal choice by either introducing one or enhancing the existing one. This allows to skip pre-transformational [[vertical]] and post-transformational [[horizontal]] steps for productions with a top-level choice, which is the most common use of this transformation. However, it is useful to have a command at hand that is capable of adding alternatives to any particular place of any grammar production rule.

## Syntax
### Syntax
```
[horizontal] add:
marked-production
```

Markers must denote the new part: i.e., the production rule without the marked part must be present in the grammar, and if it is, the result will contain a production with the marked part instead. Obviously, the markers itself do not end up in the grammar.

There are two operators that are very similar to the vertical add operator: [[define]] and [[introduce]]. The define operator should be used when an the definition of an undefined nonterminal is added. The introduce operator should be used when a fresh nonterminal is to be defined.

## Syntax
### Syntax
```
[vertical] add:
production
```

Vertical addition operates on the level of productions: it adds one more production for some nonterminal to any number of productions that are already present in the grammar.
