Temporarily Hide IntelliSense

Here's how you might word this to be a little more clear:

When IntelliSense is invoked in Visual Studio it can sometimes obscure text or information from the code block below the line you're editing.

To momentarily reveal the covered area below the IntelliSense window, press and hold the CTRL key and the window will go semi-transparent. Release CTRL to restore IntelliSense.

Cheers.
