Where is the triangle to zero out the X & Y coordinates when trying to move an object?

Where did the triangle to zero out the X & Y coordinates with transforming? I used to use it all the time when repeating objects for making patterns. I would select my object and be able to move it the exact amount of inches I needed and I always clicked the triangle so it would 0 out instead of starting where the object is on the canvas. This is what it looked like, attached.
