Hello Guido

Locate, LocateEx may use the current index, but will work without or even may not use the current index. Also, they are more an universal way.
FindKey, SetKey / GotoKey always use the current index. They are more a BDE / TClientDataSet way.
All methods are the similar fast, when using an index. Only FindKey, SetKey / GotoKey guarantee, that index is in use.
