Yes, there is a shortcut key for italics in Microsoft Word. You can use the Ctrl + I keys to quickly italicize a selected text.

If you want to customize your own shortcut key for italics, you can do so by following these steps:

1. Click on the "File" tab in the top left corner of the screen.
2. Click on "Options" at the bottom of the left-hand menu.
3. Click on "Customize Ribbon" in the left-hand menu.
4. Click on "Customize..." button next to "Keyboard shortcuts" at the bottom of the screen.
5. In the "Categories" box, scroll down and select "Format".
6. In the "Commands" box, select "Italic".
7. Click in the "Press new shortcut key" box and press the keys you want to use as your shortcut for italics (e.g. Ctrl + Shift + I).
8. Click "Assign" and then "Close".

Now, whenever you want to italicize a selected text, you can use your customized shortcut key instead of using the Ctrl + I keys.
