All I find from googling "disable incremental search" is a bunch of people telling me how great incremental search is. It isn't. Firefox has the worst version of it, jumping around and making me lose my place because of a search I haven't even finished typing yet. I don't want the window scrolling up and down without my say-so.
It would be nice if I could search with regular expressions, like text search has been done in every non-toy application since
ed. But the jumpiness of the window is the overriding concern.
How can this evil be defeated?
I see now that I was unclear in specifying exactly which user interface element I was talking about. I'm talking about the simple text search that you can get to by typing Control-F or using "Find" in the Edit menu. I should have specified that originally. Sorry for the waste of time caused by the ambiguity.
