Description Joshua Bell 2012-11-13 17:04:35 UTC 
In some scenarios, it is beneficial to avoid the cost of deserializing values when walking a cursor across an object store. IDBIndex has openKeyCursor, and it wouldn't be difficult to support the same method on IDBObjectStore.

Excellent summary of the use cases in this message:

We shouldn't add this to v1, but it's a nice simple addition to v2.
