# Inserting Formulas

When working with mathematical or chemical formulas, they can be inserted as an image in formattable text fields, such as knowledge items, abstracts, or tables of contents.

- Generate the formula in an external editor (such as the Word formula editor).
- Copy the formula to the Clipboard (Ctrl+C).
- Switch to Citavi and create a new quotation for the reference.
- On the Edit menu, click Insert formatted (Ctrl+Shift+V).

Note: Citavi converts the pasted formula to a picture, so it cannot be edited in the formula editor. Be sure to save the original file from the editor. In the Abstract, Table of contents, Quotations, and Thought fields images cannot be inserted without any accompanying text.

If you are using TeX, you can also use Citavi's formula editor.
