Creating an em dash on Windows is simple. An em dash is a long dash that adds flair to your writing. To make one, hold down the “Alt” key and type “0151” on the numeric keypad. This quick guide will help you master the em dash and enhance your writing.
How to Em Dash on Windows
Creating an em dash adds a touch of professionalism to your text. These steps will teach you how to insert an em dash on a Windows computer.
Step 1: Open Your Document
Open the document where you want to insert the em dash. This can be any text editor, like Word or a web browser text field.
Having your document open is important because you’ll insert the em dash directly where your cursor is placed.
Step 2: Position Your Cursor
Place your cursor where you want the em dash to appear.
Positioning the cursor is crucial so the em dash appears exactly where you need it in your text.
Step 3: Activate Num Lock
Ensure Num Lock is turned on. This allows the numeric keypad to function properly.
The numeric keypad won’t work for special characters unless Num Lock is activated.
Step 4: Hold Alt Key
Press and hold the “Alt” key on your keyboard.
Holding the Alt key lets you input special characters using the numeric keypad.
Step 5: Type “0151” on Numeric Keypad
While holding “Alt,” type “0151” on the numeric keypad.
Typing “0151” is the specific code for the em dash—be sure to use the numeric keypad, not the numbers above the letters.
Step 6: Release the Alt Key
Release the “Alt” key.
Releasing the Alt key completes the process, and your em dash will appear where the cursor is placed.
After completing these steps, your document will feature an em dash exactly where you intended. It’s a simple way to make your writing look neat and polished.
