I have a .xls spreadsheet with several thousand client comments. I would
like to search specific key words/phrases that appear throughout the comments
to discover what they are saying collectively about our "customer service",
"payment plans", "support", etc.

I can use Edit--Find--All to get a pop up in which I can type a key
word/phrase and produce a list of the cells containing the key words/phrase I
am searching, and I can scroll through the list to see them one-by-one, but I
would like to export or group those specific cells with together into another
spreadsheet so I can work them separately as a subset with a common theme.
How can I do that???
