As far as I know, there is no way to scroll that down in any other way with that particular GUI.
You pretty much have several possible options, though. The easiest option would be to use slash commands (I assume there are grid slash commands to change the texture). You may also be able to find an addon GUI that will provide the arrows/a better layout. Editing the SavedVariables file is another possibility - the only one I know for sure would work - but it would be by far the most frustrating option, unless you know exactly how you want to change it.
