convert/rotate subdivisions

Support Modeling

Hello. I’m trying to recreate a simple series of moves in edit mode and I can’t remember how I did it.
I want to cleanly rotate/convert the mesh to look like this:

so then I could do stuff like this

I know the screw and other tools do this but there’s a way to do this simply in edit mode. Bothering me that I didn’t save this info. Not sure if I saw it in a video or a photo tip on facebook. Any help much obliged.

Select the faces, ctrl+E -> un-subdivide with odd number of iterations.

Perfect. Odd numbers. I was trying negative and not un-sub. Oh boy. Well now I can sleep better tonight. Thanks JA12.
