What Does Underlining Do?

Underlining is a form of text formatting that draws a line beneath selected words or characters. It is often used for emphasis, headings, hyperlinks, or to highlight specific parts of a document.

Examples of where underlining is commonly used

  • Emphasizing key terms in essays

  • Highlighting titles or names

  • Formatting links in web content

  • Indicating blanks or spaces in printed forms

The general shortcut for underlining text is

  • Ctrl + U (Windows)

  • Command + U (Mac)

This command works in most word processors and text-editing applications. Simply highlight the text you want to underline and press the shortcut key.

Underline Shortcut in Microsoft Word

Microsoft Word is one of the most widely used word processors. The underline shortcut here is consistent with other Windows programs

  • Ctrl + U Toggles underline on or off

  • Ctrl + Shift + W Applies underline to words only (not spaces)

  • Ctrl + Shift + D Applies double underline

These options give you more flexibility depending on the formatting style you need.

In Google Docs, the same shortcut works

  • Ctrl + U (Windows)

  • Command + U (Mac)

After selecting the text, pressing the shortcut will apply or remove the underline effect. Google Docs also allows users to apply underline through the Format menu, but using the shortcut is faster.

Underlining in Excel and Spreadsheets

Although spreadsheets are not typically used for long texts, underlining can be helpful in formatting cell content. In Microsoft Excel or Google Sheets

  • Ctrl + U (Windows)

  • Command + U (Mac)

These keys underline the content inside a cell. Note that you must double-click the cell or enter edit mode first to underline specific parts of the text.

Many modern email services and web-based text editors also support the underline shortcut.

Examples

  • Gmail

  • Outlook Web

  • Slack messages (in some formatting modes)

  • Text boxes in forums or blogs

As long as the platform supports rich text editing, Ctrl + U or Command + U will generally work.

Good Uses

  • Emphasizing key words

  • Denoting hyperlinks

  • Drawing attention to headings

Avoid Using Underlines

  • Along with bold or italics on the same text (unless necessary)

  • In documents meant to be printed in black and white where lines may appear unclear

  • In place of headings or bullets that serve a better organizational role
