Find and replace text across all sheets in presentation mode
Open the Find panel to search every sheet of a presentation and replace matched text.
In presentation mode, Find (Find and Replace on the Home toolbar) opens a panel with a Find box, a Case Sensitive tick box and a Replace box.
Find counts the matches across all the presentation's sheets, not just the open one (for example '1 of 2 matches' for a text on two sheets, with two arrow buttons beside the count).
Find offers Replace and Replace All.
