"Key Lookup" shows up as "Clustered Index Seek"

[BrentOzar]

In SSMS, an operation that shows up as a "Key Lookup" in the plan, shows up in html-query-plan as a "Clustered Index Seek."

Here's an example plan:

If you go to the XML tab, copy the xml, and save it to disk as a .sqlplan file, and open it in SSMS, it shows as a Key Lookup.

In the plan XML this appears as a "Clustered Index Seek", however it looks like this is for some sort of backwards compatibility reason. The lookup="true" attribute indicates that this is a Key Lookup. Documentation is here:
