In a spreadsheet, the Undo and Redo commands work like they
do in a word processing document.
The Undo command will undo
the last thing you did to
a spreadsheet. You'll undo when you make a mistake
and want to go back a step.
The Redo command lets you
redo steps in case you
accidentally undo too many times.
Next, you will practice changing the size of the columns
and rows in the spreadsheet, and then you'll undo the changes.
