UltimateKEYS Keyboard Layout (Windows/Linux)

International US QWERTY layout with AltGr (Right Alt) dead keys via AutoHotkey script (Win), MSKLC source (Win, obsolete) and XKB integration (Linux, experimental).
GitHub Release

In UltimateKEYS, all keys remain exactly organized as US QWERTY. Except, when AltGr (Right Alt) or AltGr+Shift (Right Alt + Shift) is pressed in combination with another key, other diacritics and symbols are accessible and some keys become dead keys.

In that way, it is - somehow - similar to the layout "United States-International" (on Windows), although this project moves all dead key combinations to the modifiers AltGr and AltGr+Shift. That way, this project solves the most typical issues, among which the quotes (' and ") can be used as usual (without pressing the space bar afterwards), while the acute accent (´) and diaeresis (¨) are found on AltGr+' and AltGr+Shift+" respectively. This project has adopted several aspects from EurKEY (by Steffen Brüntjen).

Additionally, recent releases also feature "Smart error-tolerant optimization for circumflex in French", allowing you to type the letters â/Â, ê/Ê, î/Î, ô/Ô, û/Û more easily.

Installation - AutoHotkey Script (recommended method for Windows)

The AutoHotkey scripts are highly customizable editions of UltimateKEYS. To work properly, the Windows keyboard has to be set to standard US QWERTY and at least AutoHotkey v1.1 is required.
