How to rename multiple test plans at a time in the test plan module.

The reason why i am asking this question is every time if i wanted to change the name of the test plans i am pressing the funtion key F2 and renaming them.Well this is becoming very difficulty to do it.Is there any automatic way or any vb Code to make this renaming automatic.
Please help me.
Thanks in Advance
