# Glossary

A glossary explaining the terms commonly used in Slate:

## Anchor

## Block

## Blur

## Change

## Character

A "character" is the smallest element that makes up a text node in Slate.

## Collapsed

## Core

## Data

## Decoration

## Document

The "document" is the top-level ["node"](/slate/general/glossary.md#node) that contains all other nodes that make up the content of the Slate editor.

## Editor

## Extend

## Focus

## Fragment

## History

## Inline

## Key

Keys are unique identifiers given to nodes in Slate to be able to reference them uniquely even as the document changes.

## Mark

## Merge

## Model

## Node

## Normalize

## Offset

An offset is a distance from the start of a text node, measured in ["characters"](/slate/general/glossary.md#character).

## Operation

## Placeholder

## Plugin

## Point

A point represents a specific location in a document, where a user's cursor could be placed. It is represented by the `key` of the node in the document, and the `offset` of characters into a node.

## Range

A range is a way to represent a specific section of a document between two ["points"](/slate/general/glossary.md#point). It is modelled after the [DOM Range](https://developer.mozilla.org/en-US/docs/Web/API/Range) concept.

## Redo

## Rule

## Schema

## Selection

## Serializer

## Split

## Stack

## Text

## Undo

To "unwrap" is the opposite of to ["wrap"](/slate/general/glossary.md#wrap), removing a surrounding node from a selection.

## Validate

## Value

## Wrap

To "wrap" is to surround a piece of text or a node in another node. For example, if you select the text `Google` and want to turn it into a link, you'd "wrap" it with an inline link node.
