Level and group selection 

To select the Level 2 (commonly called “shifted”, see the subsection “Levels and Groups” of the section “ISO/IEC 9995-1” above), two keys shall be present in row B (commonly called Shift keys). The left one shall occupy position B99, while the right one shall be located right of the character input keys of that row. The exact function of these keys (commonly pressing them together with the affected character input key) is not specified in the standard. Thus, solutions where the shift key is pressed, then released before the character input key is pressed, are compliant with the standard.

To select the Level 3 (if this is present on a layout), at least one Level 3 select key (frequently marked AltGr) shall be present. On keyboards compliant to the “harmonized 48 graphic key keyboard arrangement” (see above), such keys shall be placed in row A or row B. Like for the shift keys, the exact function of these keys (commonly pressing them together with the affected character input key) is not specified in the standard.

For layouts containing more than one group, several mechanisms for group selection are specified. A dedicated Group selection key (marked by  according to ISO/IEC 9995-7), if present, shall be positioned adjacent to a “Level 3 select” (AltGr) key. For layouts containing a “Group 2” as specified in ISO/IEC 9995-3, this key shall work as a “latch” (i. e., when it is pressed and then released, the actuation of the next character input key causes the selection of a character of Group 2. After this, the status is reverted, thus subsequent character input key actuations refer to the basic group unless the “group selection” key is actuated again). If no dedicated “Group selection” key is present, its function is obtained by pressing the “Level 2 select” and “Level 3 select” (i. e. “Shift” and “AltGr”) key simultaneously and releasing them before actuating the selected character input key.

 Level and group selection 

 To select the Level 2 (normally called “ shifted ”, see the subsection “ Levels and Groups ” of the part “ ISO / IEC 9995 - 1 ” above), two keys shall be present in row B (normally call Shift key). The left one shall occupy place B99, while the correct one shall be located justly of the character input key of that row. The exact function of these key (commonly pressing them together with the affected fictional character input key) is not specified in the standard. Thus, solution where the shift key is pressed, then released before the character stimulation key is pressed, are compliant with the standard. 

 To select the Level 3 (if this is present on a layout), at least one Level 3 select key (frequently marked AltGr) shall be present. On keyboards compliant to the “ harmonized 48 graphic cardinal keyboard agreement ” (see above), such key shall be rate in row A or row B. Like for the switch key, the exact function of these key (commonly pressing them together with the affected character input winder) is not specified in the standard. 

 For layouts containing more than one group, respective mechanisms for group excerpt are assign. A dedicated Group selection key (marked by   harmonize to ISO / IEC 9995 - 7), if present, shall be positioned adjacent to a “ Level 3 select ” (AltGr) key. For layout containing a “ Group 2 ” as specified in ISO / IEC 9995 - 3, this key shall work as a “ latch ” (i. e., when it is iron and then released, the propulsion of the next character input key causes the choice of a character of Group 2. After this, the condition is reverted, thus subsequent fictional character input key propulsion refer to the basic group unless the “ group selection ” key is actuated again). If no dedicated “ Group selection ” key is present, its function is obtained by pressing the “ Level 2 select ” and “ degree 3 select ” (i. e. “ Shift ” and “ AltGr ”) key simultaneously and releasing them before motivate the selected character remark key.
