The term sgCaps describes the usage of Caps Lock to totally change the behaviour of certainn keys when Caps Lock is activated (it originates from some swiss german layouts, which allow you to type german umlauts like ä and french or italian accents like é comfortably on one keyboard).

On Windows I used the Microsoft Keyboard Layout Creator to create my custom keyboard layout, which kind of joins an english, german and french layout. Just to have an example for the key o:

when Caps Lock is not pressed the key behaves like this:

without modifier: o
with SHIFT: O
with ALT GR: ö
with ALT GR + SHIFT: Ö

with activated Caps Lock the key behaves like this:

without modifier: ö
with SHIFT: Ö
with ALT GR: œ
with ALT GR + SHIFT: Œ

So basically in the keyboard layout I define 8 mappings for each key: four with caps locks deactivated and four with caps lock activated.

Can I achieve a keyboard layout like this on Linux e.g. with xmodmap? And if yes, how?

Kind regards Bastian
