How to force text wrap or enter a linefeed?

[xcel_refugee]

The equivalent Excel command is alt-Enter. It's a very important capability yet I can't find reference to it anywhere.

Please advise how I can start a new line within a cell.

In PlanMaker, it's Ctrl+Enter.

I have a mailing list with LNAME, FNAME, ADDR1, ADDR2, CITY, STATE, CODE all in one cell with each data item separated by a comma. I can force the text wrap after each item by typing CTL+Enter. Can I use SUBSTITUTE() change the commas into a 'Ctl+Enter' or '^p'? I want all the data in a single cell stacked on top of each other not run out on a single line. Doable?
