How to type an em dash on a Mac: Shift, Option, Hyphen, and fixes for 2026

The shortcut for an em dash on a Mac

Press Shift, Option and Hyphen at the same time. The em dash appears at your cursor. Hold the three keys together, then let go. On a US keyboard, the Hyphen key sits in the top row, next to the zero key.

The same key gives you a shorter mark without Shift. Option and Hyphen together type the en dash. A third-party Mac guide from Typesnap lists the em dash combination, and other third-party guides list the en dash one. Apple's current help pages do not list either one by name. So test both before you rely on them.

Test the shortcut in a plain text box

1. Open a plain text box, such as a blank Pages document or a new note.
2. Click where you want the mark to go.
3. Hold Shift and Option together.
4. Press Hyphen, then let all three keys go.
5. Compare the result with the table below. A long dash means em dash. A shorter dash means en dash.
6. If nothing appears, check your keyboard layout. The layout section later in this guide explains how.

Run the test three times. Note the mark each time, and check the length against a known em dash. A single good result can be luck, while three in a row tells you the combination works on your keyboard layout.

Which dash is which on a Mac

The em dash is the longest of the three. The en dash is shorter. Keep the names straight, because an editor notices the wrong mark quickly. When you are unsure, read the sentence aloud. A break needs the em dash. A range needs the en dash.

Why the em dash is hard to find on a Mac

Your keyboard has a Hyphen key. It does not have an em dash key. The mark sits behind a combination of modifier keys, which are Shift, Option, Control and Command. You need to remember the combination, because nothing on the keys reminds you it is there.

Most people use the mark now and then. Writers use it more often. A feature story, a thesis chapter or a grant narrative can hold many breaks. Each break that needs a search costs a little focus. The cost per dash is small, but it repeats.

Why the same keys give different results

The same keystrokes can produce different marks depending on the app. The Mac does not decide everything. Word and Google Docs run their own punctuation rules, and those rules can change the mark after you type it.

Microsoft's reference for Word says two consecutive hyphens are replaced as you type. If the hyphens have spaces on both sides, Word uses an en dash. If there are no spaces after them, Word uses an em dash. Spacing decides the mark, not the keys you pressed.

Google Docs is less clear. Third-party guides disagree about whether two hyphens become an em dash by default. Google's auto-correct help page does not say either. Test the behavior in your own document before you count on it.

Fix it in Microsoft Word on a Mac

Word can make the mark for you, so you may not need a shortcut at all. Open Word's AutoCorrect dialog and find the AutoFormat As You Type tab. Microsoft says those settings live in that tab. Look for the option that replaces symbols, and make sure it is on.

Here is a worked example. Type the word ready, then two hyphens, then the word you, with no space after the hyphens. Word turns the two hyphens into one em dash. The break joins the two halves with no gap on either side.

If you add a space after the hyphens, you get an en dash instead. That is the spacing rule at work, not a broken keyboard. Keep the spacing that matches your style guide, and check it on a sample sentence first.

Microsoft's smart quotes page adds one more detail. A quote that follows an em dash is formatted as an opening quotation mark. If a closing quote looks wrong after a break, check the quote marks as well as the dash.

Fix it in Google Docs on a Mac

Google's help page for auto-correct gives the path on a computer: Tools > Preferences > Substitutions. The page shows a checkbox for automatic substitution. Open that list, read which rules are on, and keep the setting you need.

The page also says the feature cannot be used on Android or iPhone and iPad. That is fine for Mac work, but your phone may behave differently. If Google Docs does not convert two hyphens on your Mac, use the shortcut. Do not wait for the app to do it.

Set up a text replacement for the em dash

A text replacement turns a short code into the mark. Apple's help page describes the path: System Settings > Keyboard > Text Replacements. Apple also warns that text replacements, smart quotes and dashes, and smart links aren't available in all apps. Test it in each app you use.

1. Open System Settings > Keyboard > Text Replacements.
2. Click Add to start a new entry.
3. In the first field, type a trigger you never type by accident, such as emd.
4. In the second field, paste an em dash copied from a document where you already have one.
5. Click Add, then Done.

Type emd in a plain text box, then a space if your app needs one. If the mark appears, the rule works there. If it does not, the app may block smart dashes. Use the shortcut in that app instead.

Pages and other apps on your Mac

Run the same test in Pages, Notes and Mail before you write a full draft. Each app can handle dashes in its own way. Apple's text replacement page says smart dashes are not available in every app, so the test is the only sure check.

Keep a short list of the apps where the shortcut works, the apps where a text replacement works, and the apps where you need to paste. A list of three lines is enough. Refer to it when you start a new project.

Check which dash you typed, then fix it

Wrong marks are common. You may type an en dash and think the shortcut failed. Zoom in on the text. The em dash is longer. Compare two marks in the same font, one after the other, so the difference is clear.

To fix a mark, put the cursor after it, press Delete once, and retype. Do not select the whole paragraph to swap one character. That can change spacing and styles in the rest of the text.

When the em dash is the wrong tool

Some places expect a plain hyphen. Code, file names and search boxes often work better with the hyphen key. Check where the text is going before you paste a fancy mark. A mark that looks right in a memo can break a filename or a query.

Copying a mark from another document also works. The copy can carry a different font or spacing, though. After you paste, zoom in and compare the mark with the text around it.

Why writers second-guess the em dash now

Some writers avoid the mark because they hear that it looks machine-made. A preprint on arXiv by Przemysław Czuma looked at em dashes in 69,632 medRxiv Discussion sections, deposited from 2020 to 2025. The share rose from 4.23% before ChatGPT to 11.58% after it.

The author calls this a population-level indicator. It is not a detector of AI use for any single paper. The preprint has not been peer reviewed. Read it as a trend in published text, not as a rule for your draft.

Choose the mark for clarity. Use a dash where a break helps the reader, and a comma or period where it does not. Then follow your editor's style sheet, which matters more than any trend.

What the em dash costs you in time

The dash itself costs a few seconds. The hunt for it costs more. A 2019 PLOS ONE survey put manuscript formatting at a median of 52 hours per person per year. That figure covers formatting in general, not dashes, and the sample was self-selected. Read it as a rough signal, not a measurement of punctuation.

No study times em dash typing, so measure your own week. At the BLS median of $36.98 per hour for writers and authors, one minute of hunting costs about 62 cents. Five minutes a week comes to about $3.08. Use your own hourly rate in the same math.

Mistakes people make with the em dash

• Typing two hyphens in Word and expecting an em dash, when a space after them gives an en dash.
• Using the en dash for a break in a sentence, because it sits on the same key.
• Setting a text replacement and forgetting that some apps ignore it.
• Trusting Google Docs to convert hyphens without testing the behavior first.
• Deleting every dash from a draft to avoid suspicion, which can make the sentences harder to read.

Choose one method for each app

Pick one method per app and write it down. In Word, use the conversion rule if your test works, and the shortcut if it does not. In Google Docs, use the shortcut or a text replacement, since the default is unclear. In Pages, start with the shortcut and test it.

Keep the note where you read it often. Repeat the test after a macOS update. Apple's current help pages are labeled for macOS 27, so menus and settings may shift between versions.

Where Lazur helps, and where it does not

Lazur is a voice assistant for the Mac. It lives in the notch. Hold ⌥ ⌘ and ask about anything on screen, and Lazur answers out loud. Ask where the Text Replacements list is, and Lazur draws a circle and a label around it.

When you ask how to do something, Lazur guides you one click at a time and waits for each click. That helps with AutoCorrect in Word or Substitutions in Google Docs. Lazur does not click buttons or change settings for you. You still press the keys and make each change.

Lazur can explain a dash that came out wrong, and it can point at the spot in your text. It can also draft a sentence and type it where your cursor sits. Lazur is not a plugin or add-in for Word or Google Docs.

Next steps for your drafts this week

Start with the shortcut test. Then run the two-hyphen test in Word and Google Docs. If you still struggle, set one text replacement. Writers who draft by voice can read the Word for writers page for dictation tips.
