How to Quickly Duplicate a Line in Word

Duplicating a line of text in Word is a common task when you need to repeat a heading, a table row, or a paragraph structure. Manually copying and pasting works but slows you down when you need to duplicate many lines. This article shows you the fastest keyboard shortcuts and mouse-based methods to duplicate any line in Word without breaking your workflow. You will learn multiple techniques that work in Word for Windows, Mac, and the web version.

What Does Duplicating a Line Mean in Word

Duplicating a line means creating an exact copy of a line of text and placing it directly above or below the original. This is different from copying and pasting, which requires multiple steps and can disrupt your cursor position. The feature is built into Word through keyboard shortcuts and mouse actions. No add-ins or macros are required for basic duplication.

Before using these methods, ensure your document is not in Read Mode or protected view. The shortcuts work in Print Layout, Draft, and Web Layout views. They also work in tables, bulleted lists, numbered lists, and headers or footers.

Steps to Duplicate a Line Using Keyboard Shortcuts

Keyboard shortcuts are the fastest way to duplicate a line. The following steps work in Word for Microsoft 365, Word 2021, Word 2019, and Word 2016 on Windows. Mac equivalents are listed separately.

Method 1: Duplicate the Current Line Downward

1. Place the cursor anywhere on the line you want to duplicate
   Click at the start, middle, or end of the line. The shortcut duplicates the entire line regardless of cursor position.
2. Press Ctrl + Shift + Down Arrow
   Word inserts a copy of the line below the current line. The cursor moves to the new line. Repeat the shortcut to create multiple copies.

Mac version: Use Shift + Option + Down Arrow. This shortcut works in Word for Mac 2016 and later.

Method 2: Duplicate the Current Line Upward

1. Place the cursor anywhere on the line
   Same as Method 1.
2. Press Ctrl + Shift + Up Arrow
   Word inserts a copy of the line above the current line. The cursor moves to the new line.

Mac version: Use Shift + Option + Up Arrow.

Method 3: Duplicate a Selected Line Using Copy and Paste Shortcuts

1. Select the entire line
   Press Home to go to the start of the line, then hold Shift and press End. This selects the line from start to end without selecting the paragraph mark.
2. Press Ctrl + C to copy
   Windows: Ctrl + C. Mac: Command + C.
3. Move the cursor to the target position
   Press Down Arrow to go to the next line or Up Arrow to go to the previous line.
4. Press Ctrl + V to paste
   Windows: Ctrl + V. Mac: Command + V. The line is duplicated at the cursor location.

Method 4: Move and Duplicate Using Alt + Shift

1. Place the cursor anywhere on the line
   This method moves the line first, but you can combine it with duplication by repeating the shortcut.
2. Press Alt + Shift + Down Arrow to move the line down
   Word moves the line one position downward. To duplicate, move the original line down, then duplicate the original using Method 1.

Note: Alt + Shift + Up/Down Arrow moves the line, it does not duplicate it. Use it to reposition lines after duplication.

Steps to Duplicate a Line Using the Mouse

If you prefer using the mouse, you can duplicate a line with drag and drop or the right-click menu. These methods are slower than keyboard shortcuts but useful for occasional duplication.

Method 5: Drag and Drop to Duplicate

1. Select the entire line
   Click three times in the left margin next to the line to select it. Or drag the mouse from the start to the end of the line.
2. Hold Ctrl (Windows) or Option (Mac) and drag the selection
   While holding the key, drag the selected text to the target position above or below the original. A plus sign (+) appears next to the cursor to indicate duplication.
3. Release the mouse button first, then release the key
   Word inserts a copy of the line at the drop location.

Method 6: Right-Click Copy and Paste

1. Select the entire line
   Triple-click in the left margin.
2. Right-click the selection and choose Copy
   Alternatively, press Ctrl + C or Command + C.
3. Right-click the target line and choose Paste
   Word pastes the duplicated line. Use Paste Options to match destination formatting if needed.

Common Mistakes and Limitations When Duplicating Lines

The Shortcut Duplicates More Than One Line

Ctrl + Shift + Down Arrow duplicates the current paragraph, not just the line, if the paragraph spans multiple lines. To duplicate only one line, select the line manually before using Ctrl + C and Ctrl + V.

The Duplicated Line Loses Formatting

When you paste using Ctrl + V, Word may apply the destination formatting instead of preserving the original. To keep the original formatting, press Ctrl after pasting and select Keep Source Formatting. Or use Ctrl + Shift + V on Windows to paste without formatting.

The Shortcut Does Not Work in Word Online

Word Online does not support Ctrl + Shift + Arrow shortcuts. Use the mouse-based methods or copy and paste with Ctrl + C and Ctrl + V. The web version also lacks Alt + Shift + Arrow for moving lines.

Table Rows Are Duplicated Incorrectly

Duplicating a line inside a table cell duplicates only the text, not the row structure. To duplicate an entire table row, select the whole row by clicking outside the left border, then copy and paste. Or use Tab at the end of the last cell to insert a new row.

Keyboard Shortcuts Comparison for Duplicating Lines

Action	Windows Shortcut	Mac Shortcut
Duplicate line downward	Ctrl + Shift + Down Arrow	Shift + Option + Down Arrow
Duplicate line upward	Ctrl + Shift + Up Arrow	Shift + Option + Up Arrow
Copy selected line	Ctrl + C	Command + C
Paste selected line	Ctrl + V	Command + V
Move line down	Alt + Shift + Down Arrow	Ctrl + Shift + Down Arrow
Move line up	Alt + Shift + Up Arrow	Ctrl + Shift + Up Arrow
Drag and drop duplicate	Ctrl + drag	Option + drag

You can now duplicate any line in Word using the method that fits your workflow. For repeated duplication, memorize Ctrl + Shift + Down Arrow on Windows or Shift + Option + Down Arrow on Mac. If you work with table rows often, try the Tab key trick at the end of the last cell to insert a new row automatically.
