About the keyboard charts

• The keyboard charts are designed to show what keys are available on a keyboard. This is not intended to indicate what is engraved on the keyboards of any manufacturer.

• All keyboards are shown with the latin characters as the base group. This does not indicate that all keyboard default to latin.

• Up to four positions are shown on each key.

  upper right

  Uppercase character in the alternate group. This is not shown if it matches the character in the upper left.

• Keys with a gray square under the character represent dead keys which are used to form composite characters. A composite character is typed by first typing the accent key, and then by typing a letter key. In many cases, there is no output from pressing the dead key.

• The alternate graphics characters (alt-gr) are typed by pressing and holding the key to the right of the space bar, and then typing the key. This is known in ISO 9995 as level 3.

• Alternate groups are entered by typing the left or right shift keys while holding the alt key. For Cyrillic keyboards, Cyrillic is on the left shift, and latin on the right. For bidi keyboard, the national script is on the right, and latin is on the left.

• The keyboard charts are designed for online viewing, and do not print well.
