Align and distribute objects

Evenly distribute the five diagram boxes on slide 10 horizontally so their spacing is identical, align their top edges to 120 pixels from the top margin, and group them so they move as one. Check that the group stays centered on the slide and name it ProcessBoxes_Group.

Before I hand the deck to the design reviewer, make object spacing obvious: align the icons to a single invisible guide, equalize horizontal gaps between the five boxes, show the gap measurement in pixels on the slide notes, and flag any box whose text baseline is off by more than 4 pixels.

I dragged the five process boxes into rough order but the gaps look uneven on the classroom projector and the department head will notice. I can nudge them manually or use distribute commands, but I'm unsure which will preserve the visual rhythm and keep text baselines aligned. What's the best next step to guarantee even spacing and baseline alignment for projection?
