The Keyboard Layout for Europeans, Coders and Translators - Version for Mac OS X.
This is a port of the EurKEY Keyboard layout, which features a QWERTY baseline layout (=good access to braces etc.) with quick access to commonly used accented characters and Umlauts.
Status: The whole layout should be mapped now. Please report if you find any missing characters.
Copy the two files
EurKEY.icns to your library, either system-wide (
/Library/Keyboard Layouts) or for your local user (
~/Library/Keyboard Layouts). A system-wide installation is preferred though to ensure the layout is available to all applications. (See also this Superuser answer.)
