# Activity Center (/docs/using/activity-center)

The **Activity Center** is one feed of the Substack comments, mentions and restacks you can respond to. You can like, reply, restack or resolve each one without leaving WriteStack, using the mouse or keyboard shortcuts.

## Before you start [#before-you-start]

| Requirement | Details |
| --- | --- |
| Plan | Standard or Enterprise. See [Plans and limits](/docs/account/plans-and-limits). |
| Extension | The [WriteStack extension](/docs/using/setup/browser-extension). Likes, replies and restacks are sent to Substack through it. |

Open **Activity Center** in the sidebar.

## Filter and sort [#filter-and-sort]

| Control | Options |
| --- | --- |
| Type | **All**, **Comments**, **Mentions** |
| Sort | **Newest first**, **Oldest first** |
| **Reply to next** | After you send a reply, the reply box of the next activity opens automatically. |

Click **Refresh** to load new activity. When the feed is empty, click **Check for updates**.

## Act on an activity [#act-on-an-activity]

Each item has buttons to like, reply, restack and resolve. **Resolve** removes the item from your WriteStack feed only. Nothing changes on Substack.

The restack menu also has **Restack with a Note**, to restack and add your own words.

### Keyboard shortcuts [#keyboard-shortcuts]

Shortcuts apply to the activity under your mouse pointer. If the pointer isn't over one, they apply to the first activity in the feed. They don't work while you are typing in a text box.

| Key | Action |
| --- | --- |
| `1` | Like |
| `2` | Reply |
| `3` | Restack |
| `5` | Resolve |
| `⌘ + Enter` (Mac) or `Alt + Enter` | Send a reply |
| `Esc` | Close the reply box |

## Activity Settings [#activity-settings]

Click the settings icon at the top of the page to open **Activity Settings**.

| Setting | What it does |
| --- | --- |
| **Time range** | How far back to show activity, from 1 to 6 weeks. The default is 2 weeks. Click **Save time range** after you change it. |
| **Auto-resolve liked comments** | Resolves notifications for comments you already liked. |
| **Auto-like on reply** | Likes a comment when you reply to it. |
| **Auto-resolve on reply** | Resolves a notification when you reply to it. |
| Author rules | Automatically like or resolve notifications from specific authors. Search for an author under **Search authors to auto-handle**. |

You can also set author rules from a notification: click **Auto-handle this author**. For each author you choose what happens to their **Comment replies**, **Mentions** and **Restacks**: **Like**, **Resolve**, or both. **Clear rules** removes them.

## Resolve everything at once [#resolve-everything-at-once]

**Resolve all comments** marks every comment in the feed as resolved and clears them from your Activity Center. It asks you to confirm first and shows how many comments it will resolve.

## A daily pass [#a-daily-pass]

A routine that uses only the features above:

1. In **Activity Settings**, turn on **Auto-like on reply** and **Auto-resolve on reply** once.
2. Open **Activity Center**, choose **Comments** and **Oldest first**, and turn on **Reply to next**.
3. Work down the feed. Press `2` to reply, send with `⌘ + Enter` or `Alt + Enter`, and the next reply box opens. Press `1` to like a comment that doesn't need words, or `5` to skip one.
4. Switch to **Mentions** and do the same.
5. For people who restack you often, set an author rule to like their restacks automatically.

## If it doesn't work [#if-it-doesnt-work]

- **Likes or replies don't reach Substack**: check that the extension is installed and you are signed in to Substack in the same browser. See [Browser extension](/docs/using/setup/browser-extension).
- **Old comments are missing**: raise the **Time range** in Activity Settings (up to 6 weeks).
- **New comments don't show**: click **Refresh**.
