# Highlighting and Sharing

Most publishing tools treat readers as passive consumers. Marked Share turns every shared document into a collaborative review surface with built-in highlighting and margin notes.

## Highlighting for Everyone

Anyone with permission to view a document can annotate it—no account or login required.

There are two easy ways to highlight:

1. **Selection Menu:** Select any string of text. A floating toolbar appears with options to **Highlight** or **Comment**.
2. **Keyboard Shortcuts:** Press `h` to toggle a highlight on the currently active block, or press `c` to attach a comment.

If you are doing a deep proofread, turn on **Highlight as I select** in the Highlights menu. Every selection you drag across will instantly become an active highlight without extra clicks.

## Notes and the Comments Sidebar

When you attach comments to highlights:

- A speech-bubble indicator appears in the margin next to the annotated passage.
- The **Comments Sidebar** displays all notes in chronological order alongside the document.
- Clicking any note smoothly scrolls to its exact passage in the text.
- Notes and highlights save automatically in real time—no save buttons required.

## Isolated Highlight Sets

Your annotations never overwrite anyone else's. Every reader creates their own distinct **Highlight Set**.

When you share your annotations, Marked Share generates an annotated link with a `?hl=<id>` query parameter. Anyone following that link sees the document with your specific highlights and comments overlaid.

## The Reviews Panel for Authors

If you are the author of a document, you have access to the **Reviews** panel. 

Here you can:

- See all highlight sets submitted by readers and editors.
- Inspect reader signatures and feedback in one consolidated view.
- **Import** selected review highlights directly into your own master highlight set.
- Export annotations to take them back into local tools.
