Can't find subsurf button

I’m new at blender, and I’ve been doing a tutorial. But where it said to make the object a subdivision surface I could not find the button.
It says to go to the edit buttons and it should be right there in the mesh tools right under the auto smooth.
I’m using 2.40 and I’m wondering if they moved the button to a different position, or if there is a hotkey I could use instead.
You all know how important subsurf is, so could someone help me please

arrrrghh is this deja vu? j/k just read the “Missing Button” post.


(the search is my friend :slight_smile: )

Thanks for your help

don’t we have another one of these questions in the first page? this is getting old.
