Antlr Editor mode missing in VS2019 keyboard settings options

[kaby76]

I want to set up some keyboard mappings when I'm in Antlr mode in the VS2019 editor. But, for whatever reason, I don't see Antlr listed in "Use new shortcut in", and I have no clue how to add an item here.

Looks like I need to create a custom editor.
