For example, if I'm writing C code and I want to find foo but not foo_bar, I usually do \<foo\> but really it seems that I should be doing \_<foo\_> ... fine. I can make that adjustment. But when I do incremental search, I often hit ^w to pull in the next word but what I really want (often but not always) is to pull in the next symbol (into the search string). So if I'm sitting at this_that, I'd ilke to hit ^W (perhaps) and pull in this_that instead of just this.
