The fastest way depends on which app you're using

On a Mac, subscript (small text that sits below the baseline, like the 2 in H₂O) works differently in each program. Microsoft Word has a keyboard shortcut: Command + Control + B. Google Docs uses the Format menu. Apple Pages has its own menu path. There is no single Mac-wide shortcut that works everywhere, so you need to know which app you're in.

The method also depends on whether you're typing new text or formatting text you've already written. If you're in the middle of typing and need to drop into subscript mode, a keyboard shortcut is fastest. If you're going back to fix something you wrote earlier, the menu route is usually clearer.

Key Takeaways

  • In Microsoft Word on Mac, select the text and press Command + Control + B to make it subscript.
  • In Google Docs, highlight the text, go to Format > Text > Subscript.
  • In Apple Pages, select the text and use Format > Character > Baseline > Subscript.
  • Most other apps (Notes, Mail, TextEdit) do not have built-in subscript formatting and require workarounds like copying a formatted character from elsewhere.

Microsoft Word subscript on Mac

Open your document and position your cursor where you want the subscript to begin. Type the character or number that should be subscript, then select only that text by clicking and dragging across it. With the text highlighted, press Command + Control + B. The text will shrink and drop below the baseline immediately.

To return to normal text, click after the subscript character and press Command + Control + B again to toggle it off. If you're typing a long string of subscript (like a chemical formula with multiple subscript numbers), select all of it at once before pressing the shortcut.

If the keyboard shortcut does not work, you can also go to the Format menu at the top, select Character, and look for a Subscript checkbox. This route is slower but confirms the feature is available in your version of Word.

Google Docs subscript

In Google Docs, type your text first, then go back and select the character or characters that should be subscript. With the text highlighted, click the Format menu at the top of the page. From the dropdown, select Text, then Subscript. The selected text will immediately format as subscript.

Google Docs does not have a keyboard shortcut for subscript on Mac, so the menu route is the standard method. If you need to type subscript frequently in a document, you may find it faster to type the whole document first and then format all subscripts at the end in one pass.

Apple Pages subscript

Select the text you want to make subscript in your Pages document. Go to the Format menu in the top menu bar and select Character. A sidebar will open on the right side of your screen. Look for the Baseline dropdown menu and select Subscript from the list.

Pages also offers a superscript option in the same menu if you need text that sits above the baseline instead. Unlike Word, Pages does not have a keyboard shortcut for this, so the menu method is the only straightforward way.

Subscript in Notes, Mail, and other Apple apps

Apple's built-in Notes and Mail apps do not have subscript formatting options. If you need subscript in these apps, the workaround is to type your text in a program that supports it (Word, Pages, or Google Docs), format the subscript there, copy the formatted text, and paste it into Notes or Mail.

TextEdit, the basic text editor on Mac, also does not support subscript unless you save the document as a .rtf or .docx file first. For most everyday use, if you need subscript, it is simpler to use one of the three programs listed above rather than trying to force it into a limited app.

Copying subscript characters from the web

If you only need subscript occasionally and your app does not support it, you can search for the specific subscript character online and copy it directly. For example, searching "subscript 2" will show you ₂, which you can copy and paste into almost any app. This works in Notes, Mail, and other programs that do not have formatting menus.

The downside is that you are copying individual characters rather than formatting text, so this method only works well for single numbers or short strings. For longer subscript text or repeated use, learning the menu path in your main app is more practical.

Keyboard shortcuts and special characters on Mac

Mac has a Character Viewer tool that lets you search for and insert subscript characters directly. Press Control + Command + Space to open it, then search for "subscript" to see all available subscript characters. You can click any character to insert it at your cursor position. This works in any app, including ones without subscript formatting.

The Character Viewer is slower than using a formatting menu, but it is useful if you need a subscript character that is not a standard number or letter, or if you are working in an app with no formatting options at all.

Frequently Asked Questions

Does subscript work the same way on Mac and Windows?

No. Windows Word uses Ctrl + = (Control and equals sign), while Mac Word uses Command + Control + B. Google Docs uses the same menu path on both systems. If you switch between Mac and Windows, you will need to remember different shortcuts for each.

Can I make subscript text in an email on Mac?

Mail does not have a subscript button. You can type your email in Word or Pages, format the subscript there, copy the text, and paste it into Mail. The formatting will carry over. Alternatively, copy a subscript character from the Character Viewer and paste it into your email.

What if the keyboard shortcut is not working in Word?

Make sure you have selected the text first — the shortcut only works on highlighted text, not on text you are about to type. If it still does not work, try the Format menu route instead. Some older versions of Word for Mac may have different shortcuts or menu locations.

Is there a way to type subscript without selecting text first?

In Word, you can press the keyboard shortcut to turn subscript mode on, type your character, then press it again to turn it off. This is faster than selecting if you are typing subscript in the middle of a sentence. Try pressing Command + Control + B, typing your subscript character, then pressing the shortcut again.
