Splitting cells with EVERY carriage return

Hey guys! Could anyone tell me how to INTERACTIVELY split a sentence like "The cat likes milk" so that "likes milk" would be in a newly inserted cell just beneath "The cat" - and assign a hotkey to it? Or phaps there's a ready-made hotkey for an action like this that I don't know of?Untitled-1.jpg

I need to be able to do it interactively since I'm performing some followup editing work. Here I need to split cells so that every bold phrase would be at the beginning of a new line and hence form a new glossary entry. (see attached)

see post#3

well, for some unknown reason I couldn't upload the excel file.
however, meanwhile I've managed to solve the problem.

So,
1. I've interactively split up the cells (Alt+enter)
2. saved the data as a unicode txt file
3. imported it as txt data

voila! it worked out fine)
