Inserting a text effect, such as shadow or glow, in your document can be done in several ways. Here are some suggestions:

1. Use a text outline or box – this allows you to create a border around your text which you can then customize the color and size of.
2. Use a mask – this allows you to set a transparent shape or color behind your text and you can adjust the opacity settings.
3. Use a background image – this allows you to add a subtle text effect using a gradient or patterned background.
4. Use a text tool – this allows you to add a text effect such as shadow or glow using the formatting tools available.
