The fastest way: keyboard shortcuts in most Mac programs

On a Mac, you can type subscript (small text below the line) by pressing Control + Command + Minus. Type your number or letter, then press the same keys again to return to normal text. For superscript (small text above the line), press Control + Command + Plus.

These shortcuts work in Pages, Google Docs, Microsoft Word, and most other text editors. The behavior is when ready — you do not need to select text first. Just position your cursor where you want the subscript or superscript to begin, press the shortcut, type the character, then press it again to stop.

If the shortcut does not work in your program, the process may not support this keyboard method. Move to the menu-based approach instead.

Key Takeaways

  • Control + Command + Minus creates subscript; Control + Command + Plus creates superscript on any Mac keyboard.
  • These shortcuts work in Pages, Google Docs, Word, and most document editors without any setup.
  • If keyboard shortcuts do not work, use the Format menu in your specific program to find the subscript or superscript option.
  • Some programs like Google Docs also offer Format menus as an alternative when shortcuts fail.
  • Plain-text editors and some older programs may not support subscript or superscript at all.

Using the Format menu when shortcuts do not work

If the keyboard shortcut does not respond, your program likely has a menu option instead. In Microsoft Word, click Format in the menu bar, select Character, then check the Subscript or Superscript box. In Google Docs, click Format, then Text, then choose Subscript or Superscript from the submenu.

In Pages (Apple's word processor), select the text you want to convert, click Format in the menu bar, choose Character, then click the baseline pop-up menu and select Superscript or Subscript.

This method requires you to either select the text first or type it and then select it afterward to explore the formatting. It is slower than the keyboard shortcut but works reliably across programs that support the feature.

Why subscript and superscript matter for different documents

Subscript appears in chemistry (H₂O), mathematics (x₂), and footnote references. Superscript appears in footnotes, citations (Smith¹), mathematical exponents (x²), and trademark symbols (™). Using the correct formatting makes your document look professional and ensures the text displays correctly if someone else opens it.

If you type subscript or superscript as regular text — like writing H2O or x2 — the document loses meaning in technical contexts and looks unfinished in formal writing. The formatting also preserves your intent if the document is converted to PDF or printed.

What to do if your program does not support subscript or superscript

Plain-text editors like TextEdit (in plain-text mode) and some older programs do not support subscript or superscript at all. If you need these features, switch to a word processor: Pages, Word, Google Docs, or LibreOffice all support them.

If you are stuck in a program without support and cannot switch, you can type a note in parentheses — like writing (H2O) or x(2) — but this is a workaround, not a solution. For any document that will be read by others or shared formally, use a program that handles subscript and superscript properly.

Subscript and superscript in different document types

Google Docs preserves subscript and superscript when you share the document or export it as a PDF, but may lose the formatting if you read as a .txt file. Microsoft Word keeps the formatting in .docx files and PDFs. Pages maintains it in .pages files and PDFs, but formatting can shift if opened in Word.

If you are writing a document that will be shared across different programs or converted to different formats, test the subscript and superscript in the final format before sending it. A chemistry equation that looks correct in Pages might display as plain text in Word if the file was not saved in a compatible format.

Troubleshooting when the keyboard shortcut does not work

If Control + Command + Minus or Plus does not work, first check that you are using the correct keys. The minus sign must be on the main keyboard (not the numeric keypad), and you need all three keys pressed at once. Try the shortcut again slowly, holding each key down.

If it still does not work, your program may not support keyboard shortcuts for subscript and superscript. Try the Format menu method instead. If neither works, the program does not support these features — switch to a different editor or use the workaround of typing the text in parentheses.

Some keyboard layouts (like non-English keyboards) may map these shortcuts differently. If you are using a non-US keyboard, check your system preferences or the program's help menu for the correct key combination for your layout.

Frequently Asked Questions

Can I use subscript and superscript in Google Sheets or Excel?

Yes, both support subscript and superscript, but the process is different from word processors. In Google Sheets, you must use the Format menu (Format > Text > Subscript or Superscript). In Excel, right-click the cell, select Format Cells, go to the Font tab, and check Subscript or Superscript. Keyboard shortcuts do not work in spreadsheets.

Will subscript and superscript show up correctly if I email the document?

It depends on the file format. If you send a PDF, Word document (.docx), or Pages file, the formatting will display correctly. If you copy and paste text into an email body, subscript and superscript may not transfer — test it first by sending yourself a copy.

What if I need to type many subscripts in a row?

Press the subscript shortcut once, type all your subscript characters, then press it again to turn it off. You do not need to toggle it on and off for each character. This is faster than explore the formatting to each character individually.

Does subscript and superscript work in Notes or other Apple apps?

Notes does not support subscript or superscript through keyboard shortcuts or menus. If you need these features in Apple's ecosystem, use Pages instead. Other Apple apps like Mail and Reminders also do not support them.
