Creating Menus other than View and Edit

Hello there, I am EXTREMELY new to Confluence and Wiki Markup. I do alright with HTML and CSS though. That being said, I was wondering how I can go about creating more menus than just the "Edit" and "View" menus that default with the Theme Builder? I've been looking for a built-in way, but I don't see one, and so far haven't found any information relating to doing this. (I've seen several of the Macro guides for menus, but I'm not sure where exactly I'm suppose to input that code!)

Thanks in advance for the help, and sorry if this is a dumb question! I'm still learning my way around things. The Theme Builder has been extremely user friendly powerful so far!
