Proofreading is a critical step in creating documents, presentations, and emails. Microsoft Office and many other programs include built‑in spell checking tools, but hunting through menus to open them can interrupt your flow. Instead, there is a quick keyboard shortcut that opens or activates the spelling and grammar pane in certain applications: Alt+F10.
This shortcut is not as universally known as others, but if you work in apps like Microsoft Word or PowerPoint, it can save you valuable time. Below is a comprehensive guide on how Alt + F10 works, where you can use it, Mac equivalents, troubleshooting advice, and tips to get the most out of it.
📌 What Does Alt+F10 Do?
In supported Microsoft Office applications, pressing Alt + F10 opens the Spelling & Grammar pane or the Editor pane, depending on your version of Office:
✅ In Word: Brings up the Editor pane, which includes spelling and grammar suggestions, readability statistics, and more.
✅ In PowerPoint: Opens a similar Editor or spell check window so you can review and fix issues slide by slide.
✅ In Outlook (when composing): Launches spell check on your draft message.
The exact behavior can vary depending on your Office version and custom settings, but the main purpose is to quickly access spelling and grammar tools without using the mouse.
🗂 Where It Works
✅ Microsoft Word
Word has had built‑in spell checking for decades. With modern versions (Office 365, Word 2019, Word 2021):
- Press Alt+F10 to open the Editor pane on the right side of the screen.
- It lists spelling errors, grammar suggestions, and style improvements.
- You can use keyboard navigation (Tab, Arrow keys, Enter) to review and accept changes.

In older versions of Word, Alt + F10 may open the “Research” pane instead, so check your version.
✅ Microsoft PowerPoint
In PowerPoint:
- Open your presentation.
- Press Alt + F10 and the Editor pane appears, showing suggestions for spelling corrections within your slides.
- This is particularly helpful before delivering a presentation, ensuring there are no typos in headings or bullet points.
✅ Microsoft Outlook
When composing an email in Outlook:
- Press Alt + F10 to open the Editor pane or spelling checker.
- Review flagged words and choose to ignore or fix them, all without leaving the keyboard.
✅ Other Office Apps
Some Office apps like Publisher or OneNote may not support this shortcut directly, but you can still access spell check through menus. Alt + F10 is primarily optimized for Word, PowerPoint, and Outlook.
💻 Mac Equivalent
On macOS with Microsoft Office:
- Press Fn + Option + F10 (depending on your keyboard layout) to replicate Alt + F10.
- Alternatively, you can use built‑in menu options:
- Tools > Spelling and Grammar > Show Spelling and Grammar.
Because Mac keyboards often assign special functions to F keys, hold Fn if pressing F10 alone changes volume or brightness.
🔧FAQs
- Different Office Versions:
In some older Office versions, Alt + F10 might open the Research pane instead of the Editor pane. - Custom Shortcuts:
If you or your organization have reassigned keyboard shortcuts, Alt + F10 might not perform the default action. - Function Key Behavior on Laptops:
On many laptops, you may need to press Fn + Alt + F10 to send the correct signal to the software. - Non‑Office Apps:
This shortcut is specific to Microsoft Office and won’t trigger spell check in unrelated programs.
✨ Tips to Maximize Productivity
- Combine With Navigation Keys:
Once the Editor pane is open, use Tab and Arrow keys to move through suggestions without touching your mouse. - Use With F7:
F7 is another classic shortcut that starts a full spell check dialog. Alt + F10 is ideal for the side‑pane editor in newer versions. - Check Before Finalizing:
Get into the habit of pressing Alt + F10 near the end of your writing session to quickly catch errors. - Explore Editor Settings:
Customize which issues the Editor pane shows (e.g., clarity, conciseness) to improve your writing beyond just spelling.
✅ Why This Shortcut Is Essential
Proofreading ensures professionalism in your documents and presentations. Alt + F10:
- Saves time by skipping manual menu navigation.
- Encourages better editing habits by making spell check more accessible.
- Works seamlessly within Microsoft Office’s modern Editor pane.
Windows: Alt+F10 – Open Editor pane or spell check in Word, PowerPoint, Outlook.

Mastering Alt + F10 helps you catch errors faster and produce polished work every time. It’s a small shortcut that can make a big difference in the quality of your writing.
