locate methods for cursor

[Lilu]

Hi!
I select data into cursor. In the data selected I've got some primary key. 
Using that key I want to be able to locate to the record in the cursor 
that has the value specified as a key. For example, my key field is 
"TEST_ID". I want to move to a record that has a value 3 of field 
"TEST_ID" and to delete or udate that record. How can I do it? Thanx.
Best, Ilona Karpova
