Xcode: keyboard shortcut to navigate to next/previous breakpoint

I thought I remember a keyboard shortcut in Xcode to jump to the next breakpoint in a project. I used this to quickly jump back and forth between two sections of code I was working on. I'm worn out by looking through loads of Google results to no avail. I'm also open to an alternative way to bookmark and navigate between two places in Xcode with a keyboard shortcut. Thanks!
