Confusion About Integer String Keys

I've read the following multiple times and I still don't get it.

"""
For simplicity, integer keys (ie, {"0": "zero"}) are inaccessible by `jsonq` as integer strings are assumed to be array indexes.
"""

How can I access the string "Foo" in the following JSON response with jsonq?

```
{
  "534" : {
    "aliases" : {
      "Foo" : { }
    }
  }
}
```
