You are right.

I cannot believe that I never learned about 'M-x occur RET REGEXP RET' 
till paging thru the first set of slides!!

In the buffer of an Sweave file,

 	M-x occur RET << RET

provides a buffer with all the lines that start a code chunk. Mouse-2 on a 
line in that buffer moves the point in the Sweave buffer to that line and 
scrolls the window to display it.

Likewise, in an iESS buffer running R,

 	M-x occur RET ^[>+] RET

provides a buffer with all of the commands I've typed. For me this is a 
vast improvement over hitting 'M-p' (comint-previous-input) a zillion 
times to find a command to edit. I might have to bind this command 
sequence to its own key!

Thanks,

Chuck
