https://gerrit.wikimedia.org/r/1113797

This change added the message wkilambda-mode-selector-types-group-label: "Literals and resolvers".

A couple of questions about it:

• "Literal" is generally a common word in programming, and there's even an entry for it in the glossary: https://www.wikifunctions.org/wiki/Wikifunctions:Glossary#literal . But what are "resolvers"?
• The qqq documentation says: "Label for the literals and resolvers group in the Mode Selector". What is the Mode Selector? Or at least, what is a "mode" in this context? I have a vague guess about it, but it would be really nice to write a proper definition somewhere, for example in the Glossary.

Maybe its unclear. I followed a bit of the same style as the existing 'wikilambda-mode-selector-button-label'.
"wikilambda-mode-selector-button-label": "Label for the mode selector button for accessibility, available for screen readers. Clicking on the button opens a menu to let the user change what \"mode\" of Object this is.\n\n{{doc-wikilambda}}",
"wikilambda-mode-selector-types-group-label": "Label for the literals and resolvers group in the Mode Selector",
"wikilambda-mode-selector-delete-group-label": "Label for the delete item group in the Mode Selector",

With this change, the popover now contains groups. So there is a group with actions to move items in a list up or down (and delete).
The label you are talking about is the first group with the types to choose: a reference to an existing Object, an inline literal definition, or a function call.

Of course I am open to a suggestion to make it more clear. (maybe I should add at least that it is for screenreaders only).
"Label for a group in the popover action menu for accessibility, available for screen readers, that allows selecting a type: a reference to an existing object, an inline literal definition, or a function call."

That's what I guessed. The problem is that I couldn't find a definition of "mode" anywhere. The best place for this definition would be the Glossary. If it's complicated to edit that page, you can write it here, and I'll add it.

I see that "Change what kind of Object this is: a reference to an existing Object, an inline literal definition, or a function call" is for screen readers, as its qqq already says.

Is "Literals and resolvers" also for screen readers only? In the screenshot, I see it only in the elements inspector, but it's not an aria-label attribute, like the "Change what kind of Object this".

In any case, the term "resolvers", like "mode", needs a definition in the glossary.
