Keys while studying: Space shows the answer, 1–4 rate Again/Hard/Good/Easy, ⌘Z takes back the last rating and shows that card again, R replays the card's sounds, ⌘O opens a folder, ⌘R reloads, and ⌘1–⌘3 go to Dashboard, Review and Decks. Files also reload whenever the app comes to the front. A card that asks you to [type its answer](/card-format#notes-with-fields) has a box under the question: type, then press Return to see the answer with what you typed checked against it. Rate it with 1–4 as usual. **Review** in the sidebar studies the whole collection. Pick a deck or tag to browse its cards in a table: search (⌘F), sort by any column, and double-click a card to open its file. The selected card shows beside the table as it looks when studied; drag the divider to resize it, or hide it with **Hide Card** in the toolbar. For a card from a [note](/card-format#notes-with-fields), the note's fields are listed under it, by name, with the empty ones left out. ## Adding cards **Add Card** (⌥⌘N from any app, or ⌘N in Amgi) opens a small panel over whatever you're doing: pick a deck, type a question and answer or a cloze, and press ⌘↩. The card is appended to the end of the deck's file, which is created if needed. Return moves to the next field and ⌥↩ starts a new line; Esc puts the panel away and keeps what you typed. Turn the shortcut off in **Settings**. Next to Basic and Cloze, the menu at the top lists your [note types](/card-format#notes-with-fields); a deck with notes starts with the type most of them have. For a note, the panel shows a box for each field and says how many cards the note makes; fields left empty are left out. Drop an image or sound onto a field to copy it into the collection's `media` folder and link it there. ## Menu bar The menu bar shows how many cards are due. Its menu lists what's left today, the reviews done so far and each deck with cards to study; pick one to open it, or **Study Now** to start reviewing. While it's shown, Amgi keeps running when its window is closed. Hide it in **Settings** (⌘,). ## Saved views **Saved Views** are searches with a name. Type a search and click **Save Search** (the magnifier with a plus, next to the search field) to add one; the deck, tag or view you're browsing is part of it. Right-click a view to edit its search, give it an icon or delete it. Views are kept in `.amgi.sqlite`. Every collection starts with **Leeches** (`is:leech`): cards you have forgotten 8 or more times, which usually need rewording or splitting. ## Searching Every word in a search must match the card's question, answer, tags or note fields, ignoring case and accents. Words can also be filters: | Search | Finds cards | | - | - | | `"capital of"` | with that exact phrase | | `-paris` | without `paris` (works before any filter, too) | | `#verbs`, `#lang*` | tagged `verbs`; with a tag starting with `lang` | | `deck:french` | in a deck named `french` or under one, such as `lang/french/words` | | `q:paris`, `a:"to go"` | with that text in the question or answer only | | `meaning:apple`, `wordmeaning:go` | from a note whose field of that name has the text; leave out spaces in the name | | `is:new` `is:due` `is:suspended` `is:leech` `is:cloze` `is:basic` | in that state or of that kind | | `lapses>3`, `reviews<=5` | compared by count (`<`, `<=`, `>`, `>=`, `=`) | | `due<7`, `due<0` | due within 7 days; overdue. New cards have no due date | Anything else, such as `12:30`, is searched as text. This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
