CBQ and Query Workbench have no HELP facility to simply display statement syntax

If I am in CBQ or Query Workbench and I can't remember the syntax for CREATE INDEX, I want to type HELP CREATE INDEX and have it give me the canonical syntax for the statement. Same with SELECT. It would be additionally helpful if I typed HELP UNNEST that I get a sample statement that uses UNNEST. Otherwise I have to debug my statement one error at a time. It's very frustrating. It will be a common issue for people who are coming from SQL and don't know all of the differences between N1QL and SQL. Also SQL users are accustomed to seeing useful HELP features.
