  • Alternatively you could click the strikethrough button before you start typing, which will make any text that you type after it have a line drawn through it.
  • Either of the methods outlined above will also let you remove strikethrough from text as well.

How to Use the Microsoft Outlook Strikethrough Shortcut

While knowing where to find this text formatting button is useful if it’s something that you need to do occasionally, it may not be as fast as you would like if you are going to be using the strikethrough effect a lot.

  5. Hold down Ctrl + Alt, then press the + key on the number pad. Note that this is the number pad on the right side of the keyboard. Not the + sign above the letters.
  6. Check the box next to strikethrough. A new Customize Keyboard dialog box will open.
  7. Create a shortcut for strikethrough using a combination of Alt, Ctrl, Shift, and a letter key. For example, I used Ctrl + Alt + K.
