Having a little trouble determiniing what's actually customizable currently or not

[robmonte]

I'm just getting into HeliBoard and excited to ditch the likes of SwiftKey and GBoard. Currently a big barrier for me is the comma button as it makes the spacebar far too little for me. I enjoy having the emoji key on the left and the punctuation key on the right, so I really don't need another key dedicated to comma.

I'm trying to move the pop-up menu items onto the emoji key and completely remove the comma key from the layout but struggling to accomplish this. Are changes of this level not currently supported?

It can be done. In the advanced settings you need to change the layout of the functional keys.
Replace this piece of code:

  [
    { "label": "symbol_alpha", "width": 0.15 },
    { "$": "variation_selector",
      "default":  { "label": "comma" },
      "email":    { "label": "@", "groupId": 1, "type": "function" },
      "uri":      { "label": "/", "groupId": 1, "type": "function" }
    },

With:

  [
    { "label": "symbol_alpha", "width": 0.15 },
    { "label": "emoji", "popup": { "relevant":
        [
            { "label": "settings" },
            { "label": "clipboard" },
            { "label": "one_handed" },
            { "label": "language_switch" }
        ] }
    },

If you long-press the emoji key, you'll get this:

... I have no idea where you get these keycodes and values

You need to read the layout.md file carefully.
All information is provided. 😉

but unfortunately, long-pressing the numpad button doesn't do anything

It's impossible for me too. Maybe we'll be able to do it with the next release, as there's a commit on the subject.

no popup whatsoever

You have to replace { "symbols": with { "relevant":

Is it currently possible to add symbols to the popups on letters (i.e. on the primary keyboard layout, not a symbols layout)?

[BlackyHawky]

@e-t-l
Simply enable the "Show key hints" setting in Preferences settings.
The symbols displayed after a long press is determined by the setting “Show more letters with diacritics in popup” in the Advanced settings.
Finally, you can customize the symbols after a long press on the keyboard keys by writing for example:

    { "label": "a", "type": "normal", "popup": { "main": { "label": "%" }, "relevant":
        [
            { "label": "@" },
            { "label": "&" },
            { "label": "-" },
            { "label": "-" },
        ] }
    },

I hope this answers your question.

Thanks, I have those other settings set already. It's this last part I don't understand where to put. Would that custom code be entered in one of the options under "Customize symbols and number layouts"?

@e-t-l
No, this code must be entered in the "Languages and Layouts" settings when you want to customize your keyboard layout.
