# How to draw on your screen in a Slack huddle on a Mac

Source: https://useoverlaid.app/guides/draw-in-slack-huddle-mac

> In a Slack huddle, anyone can click the pencil on a shared screen to draw on it, in the desktop app on Mac and Windows. Slack says you can't draw when sharing a single window. For zoom, spotlight and keystrokes, add Overlaid.

Slack is one of the few call tools where everyone can draw by default, which suits quick pairing sessions.

It has no zoom and no cursor effects, so a drawing app fills a different gap here than in other call tools.

## Slack's own drawing (Included in the desktop app)

Click the pencil icon on a shared screen to draw on it. Drawing is supported in the desktop app on Mac and Windows.

1. Start a huddle and share your screen.
2. Click the shared screen to expand it, then click the pencil icon.
3. Use the group drawing icon to turn off drawing for others if you want to.

Good:
- Anyone in the huddle can draw by default
- No extra app

Limits:
- Slack says you can't draw when sharing a specific window
- No zoom, spotlight or keystroke display

## Overlaid ($11.99 once, 7-day free trial)

Adds zoom, a cursor spotlight, keystrokes and fading ink on top of a screen share.

1. Share your entire screen in the huddle.
2. Press ⌃⌥D to draw, ⌃⌥K for keystrokes, ⌃⌥C for the halo and ripples.
3. Pinch to zoom in on small text and keep drawing.

Good:
- Zoom and keystrokes Slack doesn't have
- Same tool across Slack, Meet, Zoom and Teams

Limits:
- Only you can draw
- Whole-screen share only

## Tips

- **Share the screen if you want drawing.** Slack says drawing isn't available when you share a specific window.
- **Use Slack's drawing for quick collaboration.** If a teammate needs to point back at your screen, Slack's pencil is already there.
- **Use Overlaid for demos.** Zoom and keystrokes help when you're walking someone through code or a settings screen.
