Can't get some intentions to work in EAP 9712

I can't get two of the intentions to work in EAP 9712.

How do I get "Convert Closure Arg To It" to work? What do I need to select before pressing Alt+Enter?
Here is the sample code:
def myClosure = {parameter -> print parameter}
which should be converted to
def myClosure = {print it }


How do I get "Change to End of Line Comment" to work?  What do I need to select before pressing Alt+Enter?
Here is the sample code:
/*comment line 1
comment line 2 */
x = 0x30

Thanks.
