Using ZapFast

# Using ZapFast

## Writing

Enter sends and Shift+Enter adds a line. You can swap them in Settings.
`*bold*`, `_italic_`, `~strike~`, and ```` ```monospace ```` ```` format
like WhatsApp, and a message of nothing but emoji shows large.
Mentions in a group are written with `@`; the smiley opens emoji
(searchable), GIFs, and stickers, including the stickers used on the
phone.

Right-click a message to reply, react, edit, forward, delete, or check when it
was sent, delivered, and read. Hover over a reaction to see who added it.
Editing uses the composer. Press Escape to cancel.

## Stickers

Right-click a sticker in a chat or the picker to save it. Saved stickers
appear in the **Saved** row. To import a pack, click **Find packs**, copy a
`signal.art` link from [signalstickers.org](https://signalstickers.org), and
paste it into the field. You can also open a `.wastickers` file. Animated
stickers remain animated and play on hover. Use the delete button beside a
pack to remove it. Packs are stored as WebP files on your computer.

## Attachments

Paste a picture, drop files on the window, or select them with the paperclip.
They stay above the composer until you send them, with the typed text as a
caption. Press Escape or click a file's close button to remove it. Incoming
attachments up to 64 MB download when they enter view, or on click if automatic
downloads are off. If an attachment has expired, ZapFast asks your phone to
upload it again.

## Voice messages

Voice messages play in the chat with a seekable waveform. The first play sends
a played receipt. When the composer is empty, the send button becomes a
microphone. Press Enter or the send button to send the recording, or Escape or
the delete button to discard it. ZapFast raises the volume of quiet recordings.
Starting a reply before recording includes the quoted message.

## Copying

Select and copy any message text. A selection across messages uses WhatsApp's
sharing format:

```
[18:21, 8/30/2026] Ada Lovelace: Hello from France!
[18:27, 8/30/2026] You: Sure, I will take a look
```

## Chats

The search bar finds chats by name, number, or latest message; searches all
messages stored on this computer; and finds contacts without an existing chat.
Click a message result to jump to it, or a contact to start a chat. Use
`Alt+↑/↓` to switch chats without leaving the composer.

Right-click a chat to pin, archive, or mute it for eight hours, one week, or
indefinitely. These changes also apply on your phone. Click the chat header to
see its picture, number, and group members.

## Notifications and the tray

Closing the window keeps ZapFast linked in the tray. Click the tray icon or
launch the app again to reopen it. Notifications show the chat picture and open
the chat when clicked. Muted chats do not send notifications. You can change
both settings.

Press `Ctrl+/` or click the keyboard button under the composer to list all
shortcuts.
