Changing a SharePoint list url

I hate to see % signs  in a  url and to prevent this, I try to create my urls without spacing. Doing so not only provides a clean address but also a quick and easy way for me to remember them.

However, what do I do if I accidently use spaces and end up with a list url containing % signs? 

If I have been granted "full control" to the site, I open Sharepoint Designer!

1. Once in Designer, open the site that the url belongs to 
2.  Select "All files" located within the left hand of Designer, under "site objects"
3. Select the  "lists" folder
4. Right click the list that I would like to change
5. Select "rename"
6. Type the new name and press enter
