https://en.wikipedia.org/wiki/Scroll_bar:

  Although scrollbar designs differ throughout their history, they usually
  appear on one or two sides of the viewing area as long rectangular areas
  containing a bar (or thumb) that can be dragged along a trough (or
  track) to move the body of the document. [...] The “thumb” has different
  names in different environments: on the Mac OS X 10.4 it is called a
  "scroller";[3] on the Java platform it is called "thumb" or "knob";
  Microsoft's .NET documentation refers to it as "scroll box" or "scroll
  thumb"; in other environments it is called "elevator", "quint", "puck",
  "wiper" or "grip".
