How Do I Insert a Y-Bar Symbol in PowerPoint?

The Y-bar symbol combines the letter y with a line across the top, creating a ȳ. Typically used in math and statistics, a similar symbol uses a shorter macron line over the letter to show a long vowel in linguistics. To create a Y-bar symbol with an overbar as a math character, use PowerPoint's equation or symbol tools; to create a shorter macron line, use a keyboard shortcut or the Character Map tool.

Create a Y-Bar Symbol With a Macron Bar

Use a Keyboard Shortcut

Alt-code commands use keyboard shortcuts to create symbols and special letters. There are two commands for a shorter macron Y-Bar symbol, covering uppercase and lowercase letters.

Go the the area of your PowerPoint slide into which you want to insert the symbol. To insert a lowercase Y-Bar, hold down the Alt key and type the numbers 0563 on the keyboard's number keypad. To type an uppercase Y-Bar, hold down the Alt key and type the numbers 0562. When you release the Alt key, the Y-Bar symbol inserts in the slide.

Use Character Map

Type character map from the Home screen in Windows 8; in Windows 7, search for character map in the Start menu. Open the tool when it appears in the results.

When Character Map opens, make sure the Advanced View box is checked. Choose a font that contains a Y-bar macron, such as Arial, Calibri or TimesNewRoman. Type macron in the Search For box and select Search. Or scroll through the symbol list to find the Y-Bar.

Search Character Map for macron lines.
