microsoft powerpoint – How to Find and Replace text in the Master and Layout slides?

Context

I have master slide and 60 layout slides. Do not ask why, but I would like to Find and Replace text in the dummy texts, titles in the master slide and its 60 layout slides.

What I’ve tried…

…is to switch to Slide Master, then use the Find dialog by pressing ctrl+F. However when I start the Find pressing button [Find Next], PowerPoint instantly switches back to Normal View and searches in the actual presentation content.

Question

Is there any way to Find and Replace in the master slide and its layout slides, in the dummy placeholder texts?
