How is this menu page done and forums

I was looking over some of the themes and I really like the look of this site that uses the scholar theme and have two questions about the formatting

How are the menu buttons done with the home chat documents calendar navigation items is this a setting or plugin somewhere or how would I get a menu similar to that?

Also like the clean look of the groups listing, is this standard or some other type of customization?

I'm brand new and trying to see what can be done with the themes and with buddy press so I may have some basic questions starting out. Thanks
