How do I disable this code view setting in VS2010?

I don't know whats combination of keys I performed, but now my code looks like this, with a bunch开发者_如何学C of dots!

How do I disable this? Been looking for some time and can't find it.

this shortcut will do it : Ctrl+R,W

Or the slow way : Edit -> Advanced -> and uncheck "View Whitespace"

Press CTRL + E,S. This toggles the dots.
