Function keys 

A tabulation key shall be present, occupying position D00 (i. e., the key may be wider, spanning over additional positions like D99 left of D00).

A key providing one of the functions Capitals lock (usually called “Caps Lock”), Level 2 lock (i. e. “Shift lock”), or Generalized lock shall be present, occupying the position C00. (The function “Generalized lock” is not specified in the ISO/IEC 9995 series). The specific way the Caps Lock or Shift Lock works (i. e. swapping the lock state by hitting the key, as it is usually implemented) is not specified in the ISO/IEC 9995 series. Thus, solutions avoiding the status dependency as well as the problem of inadvertent hitting (e.g., the lock key pressed together with Shift turns Shift lock on, together with AltGr turns Caps Lock on, pressed alone switches off any lock status but has no effect when no lock status is activated) would not prevent compliance to the standard.

A Return key has to be present, right of the character input keys in row C. It is recommended that it expands to row D (thus spanning over position D13 when located on position C13 as shown in the figure), as it e. g. does on the German layout.

A key providing one of the functions Backspace or Backward erase shall be present in row A or (as it is more common) Row E, right of the character input keys.

If at least one Alternate key (commonly called “Alt key”) is present, it is to be positioned left of the space bar (or, if a function key specific to the writing system supported by the keyboard layout is there, left of that key).

If at least one Control key (commonly abbreviated “Ctrl”) is present, it has to be placed leftmost in row A (as it is more common), or row B.

If a Function key (commonly abbreviated “Fn”) is present, it is to be positioned left the space bar and left of an “Alternate”

 If at least one Alternate samara (commonly call “ Alt key ”) is present, it is to be put left of the space bar (or, if a function key particular to the writing system supported by the keyboard layout is there, left of that winder). 

 If at least one Control key (commonly abbreviated “ Ctrl ”) is present, it has to be placed leftmost in quarrel A (as it is more common), or row B.
