Is there a way to make layer behave as e.g. Control when key that's not defined in it is pressed while the layer is active?

Hey there! So in keyd (linux keyboard remapping tool) there is a feature that allows a layer to "fallback" to function as one of the predefined layers like control, meta, alt or shift if a key that's pressed is not "defined" in the layer while the layer is active. Example:

[main]
capslock = overload(my_layer, escape)

[my_layer:C]
h = left
j = down
k = up
l = right

With this config, when capslock is pressed it will emit escape and when held it will activate my_layer. my_layer acts as a control for all keys except the ones which are defined in it.
Is there any similar feature in kanata? I cannot use any keyboard remapping software other than keyd because I need this feature so much.

Sure: simulator link

Oh, cool, thank you for your help. However with this config I cannot use regular control key with caps+k for control+up because of (unmap lctl). Is there a way to workaround this?

if you bind a nop key to your control key (multi lctl nop1) then you can fork on jhlk like (fork (unmod (lctl) left) left (nop1))
