Fork behavior feature

[Ziryt]

I want to try out rmk instead of my current zmk setup, but I can't seem to understand fully how Fork behavior works.
In the documentation it is just defined as is, for example:

[behavior.fork]
forks = [
  # Shift + '.' output ':' key
  { trigger = "Dot", negative_output = "Dot", positive_output = "WM(Semicolon, LShift)", match_any = "LShift|RShift" },
...

Does this mean that on any layer whenever the dot is pressed with shift it will be transformed to semicolon?
In zmk I can name my behaviors and then assign them separately, so it layer1 dot with shift will be transformed to semicolon, and in the other layer2 I will just put a dot, and it will just be a dot.

Yes

Fork behavior is similar with zmk's mod-morph, but it's "global", which means it works on all layers.

Thanks for the answer
Is there any way to make them "local"?

[HaoboGu]

you mean, the "layered" fork? yeah it's improvement and PRs welcome!
