The following chart lists keys that are available on Japanese keyboards but not on standard U.S. keyboards, as well as keys that are available on U.S. keyboards but not on the various Japanese keyboards.
On Microsoft® Windows® 2000 and with some keyboards (such as the NEC PC-98) using other operating systems, the DIK_CAPSLOCK, DIK_KANJI, and DIK_KANA keys are toggle buttons and not push buttons. These generate a down event when first pressed, then generate an up event when pressed a second time.
