Ref #2707, #2708, #2469
Unlike the previous attempts at fixing the handling of build-level
keys, this change does not change the main parsing logic, which uses
`getKey` to retrieve the key from the key map.
The fact that shell worked pre-0.13.11 means that the parsing was ok.
What this changes is just the "example" keys supplied to the parser so
the tab completion works.
