Hi I'm pretty new to InDesign so please forgive me if i'm not sure of the correct terminology. Up until recently when I was doing some basic layout design and had to space boxes next to each other I would option drag one out and these green lines would appear to help place them equidistantly. This was a great feature, though somehow i've managed to turn it off.
I have no idea what this feature was called or how enable it again so my searches haven't turned up anything.
Does anyone know how to turn this feature back on?
