IDEA: "Assign statement to new local variable"?

Question

As a long time Eclipse user, I'm playing around a little bit with IntelliJ IDEA 10. I can't seem to find out how to perform an "Assign statement to new local variable" code completion.

Feature explanation:

I type something like

new BufferedOutputStream(out)

and then hit Cmd (or Ctrl)+1 and enter, and Eclipse changes the line into:

BufferedOutputStream bufferedOutputStream = new BufferedOutputStream(out);

At the same time, I can type over "bufferedOutputStream" immediately to rename it (or select from the options "bufferedOutputStream", "outputStream" and "stream" from a dropdown).

I use this feature for absolutely every assignment, and it's an enormous time saver - this must be available in IDEA, too - but where is it hidden?

Answer 1

Refactor | Introduce Variable (Ctrl+Alt+V on Windows). Note that you don't need to select the text if it's the only text in the current line. Then you can change the variable name in-line just like you've described and press Enter to complete editing.

Another way is to use the Postfix Completion:

Type .var (or just .v to select it from the list) and confirm it with Enter.
