Anyway there's little use of the Windows key that was introduced lately (and there are still lot of keyboards that don't have this key). The same remark applies to the ScrollLock key (which is now frequently remapped to Fn+Pause/SysAttn or other similar combination using the single Windows key when there's no Fn key which is typical of notebooks). However I disagree with your opinion about AltGr+Shift combinations: it works perfectly including with the ISO 9995 definitions: the unshifted and shifted position are in the same "group". However ISO 9995 allows CapsLock to be used to create other groups instead of just reproducing the shifted/unshifted layout. It can be very useful for users in India to switch between Latin and local abugidas. It could be used as well by users writing in Arabic and Hebrew abjads, or with African (Ethiopic) or North-American syllabary scripts that are complex to map on a usable keyboard. But I think that keyboard should all have a dedicated Kana key to easily map additional groups without sacrificing other shift keys on the last row: keyboards really don't need two windows keys and so the space bar can remain with a cumfortable width (as well for the Shift key or Backspace which is too narrow on many keyboards). On the last row therre should never be more than 7 keys on both sides of the space bar, and the most external keys (Ctrl) have to remain wide). If a Kana key or present, in fact it should be to the right of the right control, or ro the right of the right Shift AltGr needs to keep some width extension compared to letter keys, and in fact could be larger than the left Alt, because it is used for entering text. The Application key is too large for me, just like the left Windows key (its extra width should be better given to the left Control key to make it a bit more central). Those that design keyboard almost never test them for real usability: they prefer slling them with many packed multimedia functions (or buttons for Calc, Mail, Web or swtiching windows, and that are rarely used). Only keyboards for gamers have some attention, but only to give them additional programmable function keys for specific games... Keyboards on notebooks are extremely poorly designed, a complete nonsense.
