Collapse summary block in visual studio 2010

I have been asking Mr Google about how I shall do i开发者_Python百科f I want my block to be collapse but not the code block. I write my code in C#.

If I understand correctly, just click on the tiny - in the left margin on the same line as the first line of the summary. Or while having the cursor in the summary, hold the Ctrl key and press the M key twice.
