'Smudge' tool in PS 9?

I've looked all over the tutorials, but I can't find anything to help. I've just got Photoshop cs 9.0, after using the Gimp previously - I was trying to follow a tutorial in PS 7, and it said to use the 'smudge' tool, rather than the 'blur' tool, but I can't find a 'smudge' tool. Another tutorial in PS 7 mentioned 'smudge' and said that you could select it by pressing 'control + R', but when I tried that, it just selected 'blur'. Does PS 9 not have 'smudge'? Is blur just as good in this version? I tried searching the Help files, and all that did was describe what the 'smudge' tool was, without stating [i]where[/i] it was. Please help!
