Some cards need a mark, a pause or a closer look. These tools do that without changing how the rest of your deck is scheduled.
## Flag a card
A flag is a colored mark for you: cards to rewrite, cards to ask someone about. There are seven, numbered 1 to 7: **Red**, **Orange**, **Green**, **Blue**, **Pink**, **Turquoise** and **Purple**.
- **During a review**: open the **More** button (**⋯**) and pick a color, or press Cmd+1 to 7 (Ctrl on Windows and Linux). Press the same key again to remove the flag. A flagged card shows a thin edge in its color.
- **In the card browser**: select cards, choose **Flag**, then a color or **No flag**.
- **To find them**: search `flag:3`. See [Search, sort and edit cards](https://priortasks.com/docs/flashcards/card-browser/).
A flag belongs to one card. The two cards of a reversed note are flagged separately. A flag does not change when the card comes back.
## Bury a card
Burying hides a card until tomorrow. Use it for a card you saw a moment ago elsewhere, or one you cannot face today. Tomorrow it comes back as if nothing happened, and its schedule has not changed.
During a review, choose **Bury until tomorrow** in the **More** menu or press -. An **Undo** button shows for a few seconds. In the card browser, select cards and choose **Bury**, or **Unbury** to bring them back. A day starts at 4:00 in the morning.
## Suspend a card
Suspending keeps a card out of every session until you bring it back. Use it for a card that is wrong, or that you want to stop seeing for good.
- **During a review**: **Suspend** in the **More** menu, or @.
- **In a deck**: the menu at the end of a row in **Cards** has **Suspend** and **Unsuspend**. It acts on every card of the note.
- **In the browser**: **Suspend** and **Unsuspend**.
- **In Stats**: the **Leeches** list has a **Suspend** button for cards you keep forgetting.
The same row menu has **Reset to new**, which sends a card back to the start, as if you had never answered it.
## Study off-schedule with Custom study
Custom study makes a session outside the daily queue. Open it from **More** in a deck, **Custom study**, or from the search icon on the Flashcards page to study every deck. When nothing is due, **Study ahead** on the Flashcards page opens it on **Review ahead**.
Pick one of five choices. The sheet shows how many cards match, then **Start**.
| Choice | Cards | Counts as a review |
| --- | --- | --- |
| **Review forgotten cards** | Answered Again in the last days you set (7 by default) | Yes |
| **Review ahead** | Due in the next days you set (3 by default) | Yes |
| **Study by tag** | Cards with the tag you pick, and its child tags | Yes |
| **Preview new cards** | The next new cards, 20 by default | No |
| **Cram everything** | Every card of the deck, in random order | No |
The numbers you set, days or cards, go from 1 to 365. A session covers the deck and its subdecks.
In the three choices that count, your answers are real reviews and change the schedule. A card you answer **Again** comes back at the end of the session. **Preview new cards** and **Cram everything** only show the cards, with **Show answer** and **Next**. Nothing is recorded, so you can look at cards again and again without affecting when they are due.
## Good to know
- Suspended cards never appear in a session, custom study included. Buried cards appear only in **Preview new cards** and **Cram everything**.
- A custom session lives only on your screen. If you reload the page, you are back to the daily queue.
