By Igor R. · Updated September 2026 Tested on Word for Microsoft 365 (Windows 11) and Word for Mac. Symbol code points follow the Unicode Standard.
Short answer: in Word for Windows, type the symbol’s Unicode hex code and press Alt + X — 2126 doesn’t work but 03A9 gives Ω, 221E gives ∞, 20AC gives €. It reaches every character in Unicode and needs no setup. On a Mac, Alt + X doesn’t exist; use Insert → Advanced Symbol or the macOS Character Viewer instead.
Tap to copy. The small code under each symbol is its Alt + X code — type it in Word and press Alt + X.
Faster still for a symbol you’ll never type again: grab it from the full symbol keyboard and paste.
Word has more ways to insert a symbol than any other app — which is exactly the problem. Some reach all of Unicode, some stop at 255 characters, and one of them inserts something that only looks like the symbol you wanted. This guide covers each method, when to use it, and the traps that make symbols break later. It’s part of the Office & Tech hub.
The four methods at a glance
| Method | Reaches | Best for | Setup |
|---|---|---|---|
| Hex + Alt + X | All of Unicode | Anything, once you know the code | None |
| Alt + numpad code | 255 characters | ° © £ ± and other common signs | Numpad required |
Math AutoCorrect (\alpha, \infty) | ~2,000 math symbols | Heavy math/Greek typing | One checkbox |
| Insert → Symbol | All of Unicode | Browsing when you don’t know the code | None |
Method 1: hex + Alt + X (the one to learn)
Type the character’s Unicode hex code, then press Alt + X. Word replaces the code with the character.
03A9+ Alt + X → Ω221E+ Alt + X → ∞2713+ Alt + X → ✓20AC+ Alt + X → €
Case doesn’t matter (20ac and 20AC behave the same), and you type the bare code — not the U+ prefix you see in documentation. It works for characters above U+FFFF too, so 1F600 + Alt + X gives 😀 in a font that supports it.
It also runs backwards. Put your cursor immediately after any character and press Alt + X — Word replaces the character with its code point, so you can identify a mystery symbol in a document. Press Alt + X again to turn it back. This is the fastest way to tell a real minus sign from a hyphen, or Greek μ from the micro sign µ.
The one real trap: if the code follows other characters that are valid hex digits (a–f, 0–9), Word grabs too many. Typing CAFE2603 and pressing Alt + X tries to decode the whole run, not just 2603. Fix: type a space before the code, press Alt + X, then delete the space — or select just the code before pressing Alt + X.
Where Alt + X works: Word and Outlook on Windows (Outlook uses Word as its editor), plus WordPad and Windows 11’s Notepad. It does not work in Excel or PowerPoint, and it does not exist in Word for Mac — see the Mac section below.
Method 2: Alt codes on the numeric keypad
The classic method still works in Word: hold Alt, type the code on the numeric keypad with Num Lock on, release.
- Alt + 0176 → ° · Alt + 0169 → © · Alt + 0163 → £ · Alt + 0177 → ±
The catch is reach: these codes address a legacy Windows code page, not Unicode, so they stop at 255 characters. Anything beyond that — arrows, most Greek letters, check marks — needs Alt + X. Codes typed with a leading zero use Windows-1252; codes without one use the older CP437 table, which is why Alt + 0176 gives ° but Alt + 176 gives a shaded block ░. Full explanation: Alt codes vs Unicode vs HTML.
No numeric keypad? The codes simply won’t fire — laptops need Alt + X instead. More fixes: why Alt codes don’t work.
Method 3: Math AutoCorrect — type \alpha, get α
This is Word’s best-kept feature. Word carries roughly two thousand LaTeX-style symbol names, but by default they only work inside equations. One checkbox frees them for ordinary text:
- File → Options → Proofing → AutoCorrect Options
- Open the Math AutoCorrect tab
- Tick Use Math AutoCorrect rules outside of math regions (leave Replace text as you type ticked)
Now typing \alpha and pressing space gives α, \infty gives ∞, \pm gives ±, \rightarrow gives →, \ne gives ≠, \clubsuit gives ♣. The codes are case-sensitive — \alpha is α and \Alpha is Α. The full list lives in that same dialog; scroll it once and you’ll find a dozen you’ll use.
Two cautions. First, the trigger fires on a space or punctuation, so \alpha alone does nothing until you type the next character. Second, \circ does not give you the degree sign. Microsoft’s own documentation calls it the degree symbol, but it inserts ∘ (U+2218 RING OPERATOR), a math operator that’s slightly larger and sits on a different baseline. For a real degree sign ° (U+00B0), use Alt + 0176 or B0 + Alt + X.
For heavy math work, Alt + = opens an equation field where all of this is on by default, and Microsoft 365 subscribers can type equations in LaTeX syntax directly. See LaTeX math symbols for the command reference.
Method 4: Insert → Symbol (when you don’t know the code)
Insert → Symbol → More Symbols opens the browser. Three parts of that dialog matter:
- Font: (normal text) shows every character in your document font rather than a single symbol font. Leave it there unless you specifically want Wingdings.
- Subset jumps to a Unicode block — Arrows, Mathematical Operators, Currency Symbols, Greek and Coptic.
- Character code and from: at the bottom tell you how to type it again without the dialog. If from: says Unicode (hex), that code works with Alt + X. If it says Symbol (decimal), it’s an Alt + numpad code instead.
There’s also a Shortcut Key button: select a character, click it, and assign your own combination — Ctrl + Alt + E for €, say. That’s the right move for a symbol you use daily.
The Wingdings trap (why your arrow breaks elsewhere)
Word’s AutoCorrect turns --> into an arrow that looks like →. It isn’t one. Word inserts a Wingdings character from the Unicode private-use area (U+F0E0) — a glyph that only renders as an arrow while that font is applied. Paste it into an email, a web form, or a plain-text file and it becomes a box, a random letter, or nothing.
The same applies to any symbol you insert by switching the font to Wingdings or Symbol and typing a letter. It’s formatting, not a character.
The fix: use the real Unicode arrow — 2192 + Alt + X gives → (U+2192), which survives everywhere. If you’d rather Word stopped substituting, un-tick the arrow entry under File → Options → Proofing → AutoCorrect Options → AutoCorrect. More on arrows: arrow symbols.
Symbols in Word for Mac
Word for Mac is the poor relation here, and most guides get this wrong: Alt + X does not exist in Word for Mac. There’s no equivalent shortcut and no Mac version of the hex trick inside Word. Your working options:
- Insert → Advanced Symbol — the Mac version of the Symbol dialog. Smaller and slower than the Windows one, but it browses the full character set and lets you assign a keyboard shortcut.
- Character Viewer — press Control + Command + Space, search by name, double-click to insert. This is the system-wide tool and usually the faster route. It handles emoji too.
- Option shortcuts for common signs: Option + Shift + 8 → °, Option + G → ©, Option + 3 → £, Option + Z → Ω, Option + 5 → ∞.
- Math AutoCorrect works on the Mac — same checkbox, under Word → Preferences → AutoCorrect → Math AutoCorrect. If you type Greek or math regularly, this is the closest thing to Alt + X you’ll get.
More Mac routes: Mac keyboard symbols.
Making a symbol repeatable
If you type the same symbol more than a few times a week, stop looking it up:
- Shortcut Key in the Symbol dialog (above) — the cleanest option, works document-wide.
- AutoCorrect entry: File → Options → Proofing → AutoCorrect Options, put a trigger like
(deg)in Replace and ° in With. Word swaps it as you type. - System-wide text replacement if you want it outside Word too — see type symbols faster.
Troubleshooting
| Problem | Fix |
|---|---|
| Alt + X gave the wrong character | The code ran into adjacent hex digits. Type a space first, or select just the code before pressing Alt + X. |
| Alt + X does nothing | You’re in Excel, PowerPoint, or Word for Mac — none support it. Use Insert → Symbol, or Alt codes in Excel. |
| The symbol shows as a box ▯ after pasting | The destination font lacks the glyph, or you pasted a Wingdings character. Check with Alt + X: a code in the F000–F0FF range means private-use, i.e. font-dependent. More: symbol showing as a box. |
| My arrow turned into a letter in an email | Wingdings again. Replace it with 2192 + Alt + X. |
\alpha doesn’t convert | Math AutoCorrect isn’t enabled outside math regions, or you haven’t typed the following space. Check the box under Proofing → AutoCorrect Options → Math AutoCorrect. |
| Alt + 0176 does nothing | Num Lock off, or you used the top number row. Alt codes need the numeric keypad. |
| My degree sign looks wrong in an equation | \circ inserts ∘ (ring operator), not °. Use Alt + 0176 or B0 + Alt + X. |
Recap
- Learn one thing: hex + Alt + X. It reaches all of Unicode, needs no setup, and runs backwards to identify characters.
- Alt codes are fine for ° © £ ± — but they stop at 255 characters and need a numpad.
- Math AutoCorrect (one checkbox) turns
\alpha\infty\pminto symbols anywhere in the document. - Never trust the
-->arrow — it’s Wingdings, and it breaks outside Word. - On a Mac: no Alt + X. Use Insert → Advanced Symbol, the Character Viewer, or Math AutoCorrect.
Frequently asked questions
How do I insert any symbol in Word using the keyboard?
Type the symbol’s Unicode hex code and press Alt + X. For example, 03A9 becomes Ω, 221E becomes ∞ and 20AC becomes €. Type the bare code without the U+ prefix. This works in Word and Outlook on Windows and reaches every character in Unicode.
Why doesn’t Alt + X work in my Word?
Alt + X is only available in Word and Outlook for Windows, plus WordPad and the Windows 11 Notepad. It does not work in Excel or PowerPoint, and it does not exist in Word for Mac. On a Mac, use Insert → Advanced Symbol or the Character Viewer at Control + Command + Space.
How do I type Greek letters in Word without the Symbol dialog?
Enable Math AutoCorrect outside math regions: File → Options → Proofing → AutoCorrect Options → Math AutoCorrect, then tick “Use Math AutoCorrect rules outside of math regions.” Now typing \alpha followed by a space gives α, \beta gives β and \Omega gives Ω. The codes are case-sensitive.
Why does my arrow symbol turn into a box or a letter when I paste it?
Word’s AutoCorrect converts –> into a Wingdings character from the Unicode private-use area, not a real arrow. It only renders correctly while the Wingdings font is applied, so it breaks in emails, web forms and plain text. Insert the real Unicode arrow instead by typing 2192 and pressing Alt + X.
What is the difference between Alt codes and Alt + X in Word?
Alt codes on the numeric keypad address a legacy Windows code page and stop at 255 characters, so they cover signs like ° © £ ± but nothing beyond. Alt + X takes a Unicode hex code and reaches every character in Unicode, including arrows, Greek letters and emoji, and it needs no numeric keypad.
How do I create my own keyboard shortcut for a symbol in Word?
Go to Insert → Symbol → More Symbols, select the character, then click the Shortcut Key button and press the combination you want, such as Ctrl + Alt + E for the euro sign. You can also add an AutoCorrect entry under File → Options → Proofing → AutoCorrect Options that replaces a trigger like (deg) with the symbol.
