I am passionate about using spreadsheets for so many things, but one in particular is giving students feedback. I will create an extra column in the spreadsheet resulting from a Google Form and reply back. Oftentimes there is more than one point that I want to address with the student. Having one massive paragraph of feedback is not ideal sometimes.

Carriage Return (Hard Return)

While typing in a spreadsheet cell, hold down the command key while you press the enter key. This will force the cursor to the next line. Holding down command enter a second time will create the extra line after each paragraph within the cell.

Note: For PC users, hold down the control key as you press enter.
