Feature request: binding inheritence or aliases about keymap-drawer

[MattSturgeon]

Thanks. I didn't know yaml had an alias system, that'll come in handy.

That does exactly what I was asking for, probably better than any of my proposals.

Hey, thanks for the nice thought out post. For this I prefer to use YAML anchors and aliases. Even though I am not a fan of most of YAML's features, this is one that came in handy frequently. Basically, you can assign an anchor to a node with &ref syntax and refer to it later via *ref, a contrived example:

LGUI: &lgui
  tap: $$mdi:monitor-dashboard$$
  held: Left
LEFT_GUI: *lgui
# above keys have identical values

RGUI:
  <<: *lgui
  held: Right
# overrides `held` field from above two

(As an aside, I find oq helpful to work with yamls, e.g. oq -i yaml -o simpleyaml can expand aliases like above and print the final result.)

You can see I (ab)use this in the keyboard layouts YAML to reduce repetition: https://github.com/caksoylar/keymap-drawer/blob/main/resources/zmk_keyboard_layouts.yaml

This is similar to your approach 1 in principle, except it is using the configuration syntax features rather than a feature from the keymap-drawer side. Let me know what you think, i.e. if that is good enough. I'd prefer to not add complexity if not needed.
