The Braille key "5" on the metal keyboard features a raised dot, adhering to the Braille system principles.

Interpretation: Braille, also known as raised or tactile writing, is a system of tactile symbols designed for the visually impaired. It is composed of different combinations of raised dots created on paper using a Braille slate, Braille writer, or Braille printer, with each cell typically consisting of six dots. Developed by the French blind man Louis Braille in 1824, hence the term "Braille" is commonly used to refer to this system. This is why there is a raised dot on the keys of metal keyboards.
