A Guide to Using ZoomIt for Presentations

What is ZoomIt?

ZoomIt is a screen zoom and annotation tool (from Microsoft’s Sysinternals suite) that’s especially useful during live presentations. It lets you:

• Zoom into parts of your screen
• Draw and highlight content
• Add quick annotations to guide your audience’s attention

I’ve found it especially helpful for keeping people engaged and making sure they don’t miss key points. This video shows how it can make a big difference, whether you’re presenting to a client or running a session in a classroom, by making everything feel more interactive and easier to follow.

1. Starting ZoomIt During a Presentation

Invoke Zoom Mode

• Default shortcut: Ctrl + 1 (You can change this in the settings panel under Zoom)
• Once activated: Your screen freezes and zooms in
• Move your mouse to pan around

Zooming In and Out

• Use your mouse scroll wheel to zoom in/out

Exiting Zoom Mode

• Press Ctrl + 1 again, or
• Press Esc, or
• Right-click

2. Drawing on the Screen

Start Drawing Mode

• Default shortcut: Ctrl + 2
• Once activated: Hold left-click and drag to draw

Adjust Line Thickness

• Hold Ctrl + scroll wheel

3. Drawing Shapes

While in drawing mode:

These are great for quickly pointing things out or highlighting key areas without breaking your flow.

4. Changing Colors

Press these keys while drawing:

The colours themselves cannot be changed however in the settings panel under Draw, you can change the default colour to something other than red. It’s a small tweak, but useful to know if you want your annotations to better match your content or stand out in a different way during a presentation.

5. Typing Text

• Default shortcut: Ctrl + 2 then hit T
• Once activated: Start typing on the screen.

You can also change the colour of the text using the same colour shortcuts (R, B, G, etc.).

6. Saving Your Screen Annotations

If you want to keep what you’ve drawn:

Key Tip to Remember

You don’t always need to press Ctrl + 1 first.

• Ctrl + 1 → Zoom mode
• Ctrl + 2 → Draw mode directly

Final Thought

ZoomIt is simple (in theory) but easy to mess up under pressure. The best way to get comfortable is to:

• Practice switching modes quickly
• Memorise 2–3 key shortcuts

Avoid overusing features during presentations. It’s there to support what you’re saying, not distract from it. f you’re constantly switching modes or over-annotating, it can break your flow and make things harder to follow. Keeping it simple helps you stay in control and keeps your audience focused on the point you’re making. Good luck!
