The thing is, and I guess you have seen that, is that the handlers are
missing the differentiation between Press/Release altogether. If you
could fix that you can use XkbFilterRec to store a flag. I think just
going more global is not the right thing to do here.

xkbActions.c needs a decent overhaul and I will do that as soon as I can
switch to XKB programming more comprehensively (my current work has a
completely different set of requirements, and I would prefer to do one
after the other).

I have a list of ideas, of what could be part of a future XKB, and
switch-group-on-release is on there. I haven't had the canceling thing.
You want to cancel the group-switch if any unrelated key is being
pressed, right? Also, another modifier?

But don't let this stop you from improving xkbActions.c.

You might want to base that on a current version.

Greetings, Dirk.
