Subscript on Mac uses built-in text formatting, not special keys
On a Mac, subscript (small text that sits below the baseline, like the "2" in H₂O) is created through the Format menu in most applications, not by pressing a dedicated key. The method varies slightly depending on whether you are using a word processor like Pages or Microsoft Word, a web browser, or another program. Most Mac applications that handle formatted text have a subscript button or keyboard shortcut buried in their menus.
The most direct route is to select the text you want to make subscript, then use the Format menu to find the text formatting options. In some programs this is a single click; in others you navigate through submenus. If you work in the same application regularly, learning the keyboard shortcut saves time.
Key Takeaways
- In Microsoft Word on Mac, select text and press Ctrl+Comma to make it subscript, or use Format > Text > Subscript.
- In Apple Pages, select text and use Format > Text > Baseline > Subscript from the menu bar.
- In Google Docs, select text and use Format > Text > Subscript, or press Cmd+Comma.
- Most web-based tools and email clients do not support subscript formatting; you may need to use a special character or symbol instead.
- If subscript is not available in your application, you can copy a pre-formatted subscript character from a character map or paste it from another document.
Subscript in Microsoft Word for Mac
Microsoft Word on Mac has a dedicated keyboard shortcut for subscript: select the text and press Ctrl+Comma (the comma key, not the period). This works in Word 2016 and later versions. If the shortcut does not work, your version may be older or configured differently.
You can also reach subscript through the menu: select your text, then go to Format > Text > Subscript. A dialog box may appear asking you to confirm; click the subscript option and then OK. To turn subscript off, select the subscripted text again and press Ctrl+Comma a second time, or use the same menu path.
Word also has a superscript shortcut (Ctrl+Shift+Comma) if you need text that sits above the baseline instead. Both shortcuts work in the same document, so you can mix them as needed.
Subscript in Apple Pages
Apple Pages (the word processor that comes with Mac) does not have a keyboard shortcut for subscript, so you must use the menu. Select the text you want to subscript, then click Format in the menu bar, select Text, and look for Baseline. A submenu will appear with options for Subscript, Superscript, and Normal.
Click Subscript and the selected text will shrink and drop below the baseline. To undo it, select the text again and choose Normal from the same Baseline submenu. Pages applies the formatting instantly, so you do not need to confirm or click OK.
Subscript in Google Docs
Google Docs offers both a menu route and a keyboard shortcut for subscript. To use the keyboard shortcut, select your text and press Cmd+Comma (the comma key). This works on any Mac in any browser.
If the shortcut does not work or you prefer the menu, select the text and go to Format > Text > Subscript. Google Docs applies the formatting immediately. To remove subscript, select the text again and press Cmd+Comma a second time, or use the Format menu and click Subscript again to toggle it off.
Subscript in other applications and web tools
Many applications do not support subscript formatting at all. Email clients like Mail, web-based tools like Slack or Discord, and some text editors have no subscript option. If you need subscript in one of these places, you have two workarounds: use a special character from the Mac character map, or copy a pre-formatted subscript character from another document and paste it.
To access the Mac character map, open Spotlight (Cmd+Space), type "Character Viewer," and press Enter. Search for the subscript number or letter you need—for example, "subscript two"—and double-click it to copy it. Then paste it into your document. This method works in almost any application, including email and web forms.
Some people also use Unicode characters or HTML entities if they are writing code or web content. For example, the subscript 2 can be written as ₂ in HTML. This approach requires knowing the specific code for each character, so it is slower than using the character map unless you work with the same subscripts repeatedly.
Subscript in spreadsheets and other Office applications
Excel and Numbers (the Mac spreadsheet applications) do not support subscript formatting in cell content the way word processors do. If you need subscript in a spreadsheet, your options are limited: you can use the character map to paste a subscript character into a cell, or you can add a note or comment outside the cell with the subscript text formatted in a separate document.
PowerPoint on Mac does support subscript through the Format menu, similar to Word. Select text in a text box and use Format > Text > Subscript, or use the Ctrl+Comma shortcut if you are in a version that supports it.
Frequently Asked Questions
Why does Ctrl+Comma not work in my Word document?
Your version of Word may be older than 2016, or your Mac keyboard may be configured differently. Try the menu route instead: Format > Text > Subscript. If that does not appear, your version does not support subscript. You can also check Word's preferences to see if the shortcut has been reassigned.
Can I make subscript permanent in a template so I do not have to format it every time?
Yes. In Word, create a style with subscript formatting built in, then apply that style to any text that needs it. In Pages, you can create a paragraph or character style with subscript as the default. This is faster than formatting each instance individually if you use subscript often.
Does subscript work in Google Sheets the way it does in Google Docs?
No. Google Sheets does not have a subscript formatting option. You can paste a subscript character from the character map, but you cannot format existing text as subscript within a cell. The workaround is to use the character map to insert pre-formatted subscript characters.
What if I need subscript in an email or text message?
Most email and messaging apps do not support subscript formatting. Copy a subscript character from the Mac character map and paste it into your message. This works in Mail, Gmail, iMessage, and most other platforms, though the character may appear slightly different depending on the font.
Is there a way to type subscript without using the menu or keyboard shortcut?
Yes, if you use subscript frequently, you can create a text replacement shortcut in Mac System Settings. Go to Keyboard > Text Replacement, add a short abbreviation (like "sub2"), and set the replacement to a subscript character from the character map. Then type the abbreviation and it will expand to the subscript character automatically.
