They are using "callouts". You can find a description here

Before we start using them, we should (as Bob Stayton recommends)
establish naming rules for the identifiers (ie. document them) and we
need to have the small marker images (there's probably some copyright
associated with those on the FreeBSD website or on Stayton's site...).
