Problem
IndexOf(s,n) is also stated as "case insensitive by default" and both takes, and is documented to take, an optional Boolean. But IndexOf(s) does not accept an optional Boolean.
Proposed Solution
Either document that IndexOf(s) doesn't take an optional Boolean and suggest the workaround (IndexOf(s,0,True)) if you want case sensitivity. Or (preferably IMO) support the optional Boolean on IndexOf(s).
Example Workflow
Alternatives Considered
IndexOf(s,0,True)
