Find usage/reference of interface methods

Hello,
A lot of times I am looking for a testcase but it is really hard to find if the project is fairly large. However I typically do remember that the testcase contained some method x. It would be really cool, if I can right click the interface method and select 'find usage' and get a pop up screen which shows something like

usage of : : <>
TestSuite name --> testcase name
TestSuite name --> testcase name

double clicking on one of the results should take you to the corresponding testcase.

Thanks

Ali
