Display mod-morph labels on keys

[carsonwick]

Mod-morph labels are not currently displayed on the keys. Is this intentional? Is there a way to get the labels to display or some other method to have the desired characters show on the keys. Thank you.

behaviors {
    umlaut: umlaut {
        compatible = "zmk,behavior-macro-one-param";
        #binding-cells = <1>;
        bindings = <&kp LA(U)>, <&macro_param_1to1>, <&kp MACRO_PLACEHOLDER>;
    };

    a_umlaut: a_umlaut {
        label = "Ä";
        compatible = "zmk,behavior-mod-morph";
        #binding-cells = <0>;
        bindings = <&umlaut A>, <&umlaut LS(A)>;
        mods = <(MOD_LSFT|MOD_RSFT)>;
    };

    o_umlaut: o_umlaut {
        label = "Ö";
        compatible = "zmk,behavior-mod-morph";
        #binding-cells = <0>;
        bindings = <&umlaut O>, <&umlaut LS(O)>;
        mods = <(MOD_LSFT|MOD_RSFT)>;
    };

    a_ring: a_ring {
        label = "Å";
        compatible = "zmk,behavior-mod-morph";
        #binding-cells = <0>;
        bindings = <&kp LA(A)>, <&kp LS(LA(A))>;
        mods = <(MOD_LSFT|MOD_RSFT)>;
    };
};

It's more or less intentional, yeah. You could try using keymap-drawer to generate diagrams externally if that's your use case. I'm not sure how it handles rendering mod-morph keys by default but I'm pretty sure it allows you to override keys when necessary.

Thank you for the reply and developing such a useful tool.

I want to show the Swedish characters. They are drawn by default when using them from the keys_sv.h from zmk_locales. E.g., if I use &kp SV_A_RING, å is displayed on the key in the editor. Would it be possible to get this existing behavior to work if the label field matches an existing character/icon? Is this something that needs to be modified in keymap-drawer?

Thanks again.

I haven't used keymap drawer myself but this section of the docs might be applicable: https://github.com/caksoylar/keymap-drawer?tab=readme-ov-file#zmk-locale-headers
