# History

> Track changes and actions across your research tables with the history panel.

## Overview

The history panel records actions taken on your tables, giving you a timeline of what happened and when. It appears as a dropdown in the main workspace when you have an active table.

Open it by clicking the history icon or pressing `Cmd` + `\` (Mac) / `Ctrl` + `\` (Windows/Linux).

## Tracked events

Blazar tracks the following types of actions:

| Event type        | Description                            | Example                                 |
| ----------------- | -------------------------------------- | --------------------------------------- |
| **Table Created** | A new table was created                | Shows the original query or prompt used |
| **Column Added**  | A new data column was added to a table | "{column_name} column added"            |
| **Row Added**     | A new entity row was added to a table  | "{entity_name} row added"               |

## Using history

The history panel helps you:

* **Understand how a table was built** — see the sequence of actions that produced the current results
* **Review what changed** — identify which columns and rows were added over time
* **Recall your research context** — long descriptions in history entries are expandable, so you can revisit the full prompt or query that triggered each action

### Expanding entries

Some history entries have long descriptions (for example, a detailed query prompt). These entries are shortened by default and show "..." at the end. Click on a truncated entry to expand it and see the full text.
