phpstorm new file without making a file

Hi,
While I'm programming, sometimes I need to dump, search and replace or edit some text without it being a file. Tho, in PHPStorm i'm forced to save the file.
In sublime I could simply press cmd+n/ctrl+n, do some text editing and copy it back to where I need it, and close the screen without saving it. In PHPStorm it seems not possible yet.
Is there any way to do this?
Thanks in advance,
Bart
