Step-by-step explanation:
To remember this, remember that the F in Ctrl+F stands for “Find”.
Ctrl+H is a similar function called Find and Replace, which allows you to search for a value then replace all instances of it with a new value.
Ctrl+R fills from the selected cell(s) and to the right.
Ctrl+E activates the Flash Fil feature, which recognizes a pattern and fills in remaining cells automatically.
