How to find in one sheet in Numbers?
When I try to search something in Numbers, it will find in all sheets. Is it possible to search in currently selected sheet only?
MacBook Air macOS Sierra 10.12.3, Numbers 4.0.5
Open the sheet and use Find & Replace.
Command-F or Edit -> Find -> Find...
For most Apple productivity apps, Command-F can be used to find text in that app.
