This section covers working with text in the IntelliJ Platform editor. It is presented in two major sections:

• Editor basics tutorial
  • Using the action system to access a caret placed in a document open in an editor.
  • Accessing position information about a caret in an editor: coordinate systems and offsets.
  • Handling actions activated by keystroke events in the editor.
• Multiple carets
  • Working with multiple, independent, carets in one editor.
  • How multiple carets affect core functionality, editor actions, typing actions, and code insight actions.
