I have a laptop keyboard with right AltGr, PrintSc and Right CTRL and a MacOS X one with right Super and right Alt.
When using one, I'd like the right ctrl to be the compose key and when using the other one, I'd like the right alt to be the compose key.
Do you know if it is possible to use the XKB options to configure that?
I tried ['ctrl:rctrl_ralt', 'compose:ralt']
but no luck so far.
['altwin:swap_lalt_lwin', 'lv3:rwin_switch', 'compose:ralt']
but it just allows me to configure the mac keyboard as expected
