Blender Tip: Turn Triangles into Quads

Issue

I made this Lego Mini Figure in LeoCad but now I notice all the triangles in the model.
For many reasons, I want to clean up this model and change the triangles into quads.
It sounds like a daunting task but it is super easy in Blender.

Lego Figure in Edit Mode

All that is needed is to select the triangles in edit mode, hit the space bar to find Tris to Quads or use the Alt + J keystroke.
