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
