choose

  Data:  fqq-
  Addr:  -

Class: class:word | Namespace: d | Interface Layer: all

d:for-each

  Data:  q-
  Addr:  -
  Float: -

Execute the specified quote once for each header in the dictionary. Before running the quote, this also pushes a pointer to the header onto the stack.

Class: class:word | Namespace: d | Interface Layer: all

d:name

  Addr:  -
  Float: -

Given a dictionary header, return the name field.

  Addr:  -
  Float: -

Increment the value stored at the specified address by 1.

Class: class:word | Namespace: v | Interface Layer: all

{{

  Float: -

Begin a lexically scoped area.

Class: class:word | Namespace: global | Interface Layer: all

}}

  Data:  -
  Addr:  -
  Float: -

End a lexically scoped area. This will hide any headers between `{{` and `---reveal---`, leaving only headers between `---reveal---` and the `}}` visible.
