Hi Tony! I'm happy to help you with this.

Unfortunately, there is no default shortcut key for strikethrough text in Microsoft Word. However, you can create a custom shortcut key to apply strikethrough formatting to text.

Here's how to create a custom shortcut key for strikethrough text:

1. Click on the "File" tab in the top left corner of the Word window.
2. Click on "Options" at the bottom of the left-hand menu.
3. In the Word Options window, click on "Customize Ribbon" in the left-hand menu.
4. Click on the "Customize..." button next to "Keyboard shortcuts" at the bottom of the window.
5. In the "Categories" box, scroll down and select "Format."
6. In the "Commands" box, scroll down and select "Strikethrough."
7. Click in the "Press new shortcut key" box and press the keys you want to use as the shortcut key for strikethrough text. For example, you could use "Ctrl+Alt+S".
8. Click the "Assign" button to assign the shortcut key to the "Strikethrough" command.
9. Click "Close" to close the "Customize Keyboard" window.
10. Click "OK" to close the Word Options window.

Now, whenever you want to apply strikethrough formatting to text, you can simply select the text and press your custom shortcut key (e.g. Ctrl+Alt+S).
