International US QWERTY layout with AltGr (Right Alt) dead keys via AutoHotkey (Win), MSKLC (Win) and XKB/Xmodmap + .XCompose (Linux).
UltimateKEYS keeps all keys exactly like US QWERTY, but holding down AltGr (Right Alt) or AltGr+Shift (Right Alt + Shift) makes other diacritics and symbols accessible, and turns some keys into dead keys.
This way, it shares some similarities with “US-International”. However, this project attempts to solve the most common difficulties from its counterpart.
One of those : the quotes issue, with ' and " now accessible as usual. The similar-looking diacritics are now found on AltGr+' and AltGr+Shift+".
Further on, UltimateKEYS attempts to harmonize languages with Latin-based alphabets on US QWERTY, and has borrowed some aspects from EurKEY (GPL v3).
=> Win/Linux : Only use “BASIC LATIN” characters (codes 32 to 126) for your Windows, Microsoft Live and Linux passwords !
Otherwise, it might be impossible to type any Unicode character higher than “Basic Latin” at the login screen/prompt (due to a different keyboard configuration) ! => ACCOUNT LOCKOUT
=> Win/Linux : ALWAYS make your system passwords VISIBLE during modification !
-> Blue keys : dead keys in combination with Right Alt (+Shift) or AltGr (+Shift).

Please, give this website a try in dark mode (browser/system settings), it really looks marvel[l]ous ! 😇
Note : ‘AltGr’ is an abbreviation for ‘Alt(ernate) Graph’.
