Triggering keypress when a key is released alternatively defining layer with foreign language characters

[Goby56]

I've been at this problem for quite a while now and can't figure out how I am supposed to make it work.

Essentially what I want is to be able to type the swedish characters å, ä, ö on my US keyboard when holding CapsLock.

I've tried defining a second layer for these keys but then they are not considered valid characters. Using deflocalkeys with the appropiate event.key for åäö doesn't work as I am still on a US layout so it results in the corresponding US characters at those spots (namely [';).

I then tried switching to a Swedish layout and defining the source according to what a swedish layout would look like. Additionally I defined the base layer according to the US layout my keyboard has and another layer that has the ['; keys switched with åäö. Unfortunately this had some weird results. When switched to the layer with caps I could type å and ö as I wanted but ä didn't work. I suspect this has something to do with the enter key looking different on ISO and ANSI layouts.

In the end I've resulted in setting the xkbOption grp to caps_toggle to switch between the US and Swedish layouts with CapsLock. This is, however, not exactly what I want because I only want åäö when Caps is held and not toggling to that layout. I then thought if I could use Kanata to make it so that when releasing CapsLock it results in another CapsLock to switch back to US layout.

Is this possible or should I resort to something like this which defines åäö using an AltGr modifer which I could maybe remap to CapsLock?

You can use (on-release tap-vkey ...)
