What is one excel trick that you use but no one else uses?

I recently got into a discussion with some peers about different tricks that they use in excel. I was surprised how I knew so many they didn't. I'm curious what tricks you use in excel? Here's a short list of some of mine:

Ctrl + Shift + Arrow = Instant Selection – Quickly select an entire data range without dragging.

Alt + = for Auto-Sum Magic – Instantly sum a column or row in one keystroke.

Paste Special → Values Only – Copy formulas as plain numbers to avoid breaking calculations.

Name Ranges for Easy Formulas – Give ranges a name (Sales2026) and use it in formulas instead of cell references.

Double-Click Fill Handle – Autofill a formula down your column as far as adjacent data goes—way faster than dragging.
