The fastest way to add subscript on Mac
On Mac, the quickest route to subscript depends on what app you're using. In most programs — Word, Google Docs, Pages — you can highlight the text you want smaller and lower, then use Command + Control + B to toggle subscript on and off. If that shortcut doesn't work in your app, the Format menu almost always has a Character or Text option that includes subscript as a checkbox.
For apps that don't recognize the keyboard shortcut, you'll find subscript under Format > Character (in Pages and Word) or Format > Text (in Google Docs). Click the subscript button or checkbox, and the selected text shrinks and drops below the baseline. The same steps work to turn it off — select the subscripted text again and toggle it back.
Key Takeaways
- Command + Control + B is the standard Mac subscript shortcut in Word, Pages, and most other text editors.
- If the keyboard shortcut doesn't work, open the Format menu and look for Character or Text options to find subscript as a checkbox.
- You must select the text first — highlight it before applying subscript, or the command won't do anything.
- Google Docs, Word, and Pages all support subscript, but some older or specialized apps may not have the feature built in.
Using subscript in Microsoft Word on Mac
In Word for Mac, select the text you want to make subscript, then press Command + Control + B. The text will immediately shrink and drop below the line. Press the same keys again to remove subscript.
If the keyboard shortcut doesn't respond, go to the Home tab, click the arrow next to Font, and select Character. In the window that opens, check the Subscript box under Effects, then click OK. This method works the same way every time and is useful if you're working with many subscripted characters in one document.
Subscript in Google Docs
Google Docs doesn't have a dedicated keyboard shortcut for subscript on Mac. Instead, highlight the text, then go to Format > Text > Subscript. The text will format immediately. To remove subscript, select the text again and click Format > Text > Subscript a second time to toggle it off.
You can also use the keyboard shortcut Command + , (comma) if you remember it, though many users find the menu route more reliable since it's visible and doesn't require memorizing a less common key combination.
Subscript in Apple Pages
Pages handles subscript through the Format menu. Select your text, then go to Format > Character and look for the Baseline dropdown. Choose Subscript from the list. Pages will shrink and lower the text in one step.
You can also try Command + Control + B here, though it's less reliable in Pages than in Word. If you're formatting a lot of subscript in a single document, using the Character panel keeps everything consistent and visible on screen.
When subscript isn't available in your app
Some Mac apps — particularly older ones or specialized software — don't have built-in subscript formatting. If you can't find it in the Format menu or the keyboard shortcut doesn't work, the app likely doesn't support it.
Your options then are to switch to an app that does (Word, Pages, or Google Docs all support subscript), or to manually type a subscript character if one exists. For common subscripts like H₂O, you can sometimes find the character in the Special Characters panel (Control + Command + Space), though this is slower than using the built-in formatting feature.
Subscript in email and web forms
Most email clients and web forms don't support subscript formatting. If you're typing in Gmail, Outlook web, or a form field, the subscript command won't work because these interfaces strip out text formatting.
If you need subscript in an email, write it in Word or Pages first, format it there, then copy and paste it into your email. Some email clients will preserve the formatting; others will strip it out. If the formatting doesn't survive the paste, you may need to type a note explaining what the subscript means — for example, "H2O (H with subscript 2 and O)" — or send a document attachment instead.
Frequently Asked Questions
Why doesn't Command + Control + B work in my app?
Not all Mac apps recognize this keyboard shortcut. Some older programs or specialized software don't have subscript built in at all. Try the Format menu instead — most apps that support subscript put it there even if the keyboard shortcut fails.
Can I make subscript permanent in a template?
Yes. In Word and Pages, you can format text as subscript, then save the document as a template. Any new document you create from that template will have the same formatting. This is useful if you write chemistry or math documents regularly.
Does subscript work in Apple Notes?
Apple Notes doesn't have subscript formatting. If you need subscript, use Pages (which is also free on Mac) or another app that supports it, then copy the formatted text into Notes if needed.
What's the difference between subscript and superscript?
Subscript is smaller text that sits below the baseline — used for things like H₂O. Superscript is smaller text above the baseline — used for footnotes and exponents like x². On Mac, superscript uses Command + Control + P instead of B.
