copy-word-from-line-above

["HS" <hugows@gmail.com>]

Hello!
Does anyone have a function that copies words from the line above, word
after word ?
I'd like this function so I could have something like this:

double int xxx;

Then I'd just put the cursor under that line, press <f2> (for example)
twice and would be in this state:

double int xxx;
double int

then I would continue adding the new variable.

Thanks in advance,
HS
