Bullet

The "•" symbol is known as a bullet point. In UI design, the bullet symbol is a very common typography element that can act as a separator for text or design elements. For example, bullets can split Breadcrumbs or Pagination elements with a lightweight dot.

Fun fact: The bullet symbol was specifically designed for the Monotype systems in the early 1900s to create a visual hierarchy in text. Its centered, mid-height dot shape makes it visible while being less distracting than numbers or standard letters.
