Showing more than 10 products at once in Admin View

Does anyone know how to make Zen Cart display more than 10 products at a time when viewing your products in ADMIN>Catalog>Categories/Products>?
I have two pages of 10 products each and they could all fit nicely on one admin page if I could find out how and where to change this.

Thanks,

Mike.
Zen Cart 1.3.9g

admin > config > maximum values > Maximum Categories Products Display List > set as desired

Worked great. What was throwing me was it says "Maximum Categories Products Display List" and I took this to mean only the Categories and not the items in a category. Thanks for the help.
