History extension

Undo and redo document changes with familiar keyboard shortcuts. Track up to 100 editing actions. Press Cmd+Z to undo, Cmd+Shift+Z to redo.

How it works

Automatic grouping - Changes within 500ms are grouped as one action
Deep history - Stores up to 100 undo steps by default
Smart tracking - Preserves selection and cursor position

Use case

Mistake recovery - Quickly undo accidental deletions or changes
Experimentation - Try different edits knowing you can revert
User confidence - Standard feature users expect in any editor

Commands

`undo`

Undo the last action

Groups changes within the newGroupDelay window

Example:

editor.commands.undo()

import { SuperDoc } from 'superdoc';
import 'superdoc/style.css';

const superdoc = new SuperDoc({
  selector: '#editor',
  document: yourFile,
  onReady: (superdoc) => {
    const editor = superdoc.activeEditor;
    editor.commands.undo()
  },
});

`redo`

Redo the last undone action

Only available after an undo action

Example:

editor.commands.redo()

import { SuperDoc } from 'superdoc';
import 'superdoc/style.css';

const superdoc = new SuperDoc({
  selector: '#editor',
  document: yourFile,
  onReady: (superdoc) => {
    const editor = superdoc.activeEditor;
    editor.commands.redo()
  },
});
