Edit url

How I can to edit my category and product URL?

Please can you be more explicit

Are you trying to alter how urls are formatted or just change the text in a specific category/product url?

If it's the latter, you can do this by setting the "Search engine friendly page name" property on the SEO tab when editing a product or category.

thanks a lot, on my language translate of this function is not so clearness, sorry for ugly question)
