}

The ids of the built-in ex-commands, as returned by populate; mirrors Builtins for motions / operators / text objects.

Each field’s doc gives the registered name (ex:<name>) and the usual : spelling. Not every builtin ex-command has a field: several (ex:quit-all, ex:only, ex:split, …) are reached only by name, which is how the : line resolves every command anyway. A field exists where some caller wants the id without a name lookup.
