Hi,
I found my answer (buried) in a Microsoft Office reference book and also via Google.
In case anyone else needs to have separate lines in a cell, do the following:
- Position the cursor at the end of the first line.
- Press <Alt><Enter>. A new line "appears".
- Type text, etc.
- Continue pressing Press <Alt><Enter> and typing line contents until you are done with the lines in the cell.
