Hi Barb,

I'm happy to help you with typing a tilde over the letter X in Microsoft Word.

Here are the steps you can follow:

1. Place your cursor where you want to insert the tilde over the letter X.
2. Click on the "Insert" tab in the ribbon at the top of the screen.
3. Click on "Symbol" in the "Symbols" group.
4. In the drop-down menu, select "More Symbols."
5. In the "Symbol" dialog box, select "Latin-1 Supplement" from the "Subset" drop-down menu.
6. Scroll down until you find the letter "X" with a tilde over it (should be near the bottom).
7. Click on the letter "X" with the tilde over it to select it.
8. Click on the "Insert" button to insert the symbol into your document.

That's it! You should now have an X with a tilde over it in your document.
