There is a command in Excel, which select same word in deferent cells?

Answer 1

I'm not exactly sure what you are asking, but I'll give it a shot.

Try the "Find and Replace" option which is either on the "File or Edit" Menu.

Under "Find", type in the word you are looking for. It will take you to each cell where that word is. If you want to change that word, then type the new word under "Replace".

Hope that helped.

Answer 2

Its called union(). Pretty tricky to use but lots of fun and application potential.
