PS CS6 new tool for correcting converging verticals

Hello,

I came across a new tool in PS CS6, which has been introduced in this new version that can be used to correct converging verticals. I used it a couple of times in the past and now forgot its name and how to access it.

Basically it allows me to place lines on my picture that are supposed to be parallel and the tool them straightens out the picture intelligently without distorting it too much. It is ideal to correct edges of buildings that seem to converge.

I am familiar with Free Transform and basic Lens Correction filter, so I am pretty sure it was not one of these.

Please let me know if you can locate it.

Thanks
