add menu item that just links to a site and not a page

Greetings,

I've been making pages for my resource guide for every menu item, but it's getting silly because I just want to direct people to the source. How do I add a menu item which just links to an external webpage without making a page and putting the link on there? I've been wasting hours today trying to figure this out!

Thank you,

Emily

 

OK I just found the links button off to the left on the Edit Menu tab.

I didn't see it before because I have a bunch of other buttons (7) there due to an events plugin and directory plugin putting buttons above and below it.
