# Editor

> Edit plain source with Markdown and code previews.

DocWriter is a plain source editor. The document text stays visible and is saved without Markdown escaping.

## Markdown layers

Headings, lists, quotes, horizontal rules, bold, italic, code, links, and strikethrough receive visual styling while their source markers remain in the document.

Pipe tables receive a rendered table preview. You can show the table source when you need to edit it. Fenced code blocks receive code styling and a language label.

Markdown layers are disabled for LaTeX and related source files, including `.tex`, `.sty`, `.cls`, and `.bib`.

## Source comments

Press **Command or Control and /** to comment or uncomment the current line or selection. DocWriter chooses the comment syntax from the file extension.

## Saving and undo

The browser synchronizes edits to the server owned Yjs document. The server writes plain text back to the file on a short flush cycle.

**Command or Control and Z** undoes local typing and user actions such as accepting or rejecting a proposal. Raw agent transactions are not added to the local undo stack.

**Command or Control, Shift, and Z** redoes the latest user undo step.

## Agent changes

Proposed text appears as a green addition or red removal in the editor and as a card in the comment gutter. Muting hides the proposal layers without pausing the agent.
