Keyboard shortcuts are powerful time‑savers, and one of the most overlooked yet extremely handy ones is Ctrl + 0. This shortcut performs two main functions depending on the program you are using:
✅ In web browsers and viewing tools, Ctrl+0 instantly resets your zoom level to 100%.
✅ In Microsoft Word and some other applications, Ctrl + 0 applies or removes the Normal style, restoring default paragraph formatting.
Whether you’re reading a web page that has been zoomed in, or you’re cleaning up formatting in a Word document, Ctrl + 0 is a quick fix. Below you’ll find a detailed guide to this shortcut — how it works in Microsoft Office apps, in other popular tools, troubleshooting tips, and its Mac equivalent.

What Does Ctrl + 0 Do?
- Zoom Reset: In browsers (Chrome, Edge, Firefox, Safari) and document viewers, pressing Ctrl + 0 restores the page to its default zoom level, usually 100%.

It’s simple, universal, and makes your workspace look clean and consistent in seconds.
