In my experience, a slider is an almost-ubiquitous control that looks like
this:

  Amount of sliding:
      _
  ---| |-----------------
      V
   |    |    |    |    |
Rubber                Ice

The pentagon can be dragged along the line with the mouse or moved with
keyboard arrows when it has the focus.  It's very similar to a scroll bar
except that the dragger (the thumb) does not have width (it is mounted as
if by a pin to the track) and so is used when a value and not a range (as
of visibility) is being specified.  Sometimes it appears rotated CCW by a
quarter-turn.

Sorry if that's redundant or excessively verbose, but I'm hoping to be
understood regardless of anyone's prior experience.
