585, and you're a liar. You said, and I quote, "You can move your

It doesn't.
So it was your earlier claim that was the lie then. At least that's
settled.
No, you failed your reading comprehension again.
you can make emacs move you to the source file in question by
explicitly asking it to do so.
So much for "instantly". This behavior is definitely less awkward than
what you originally implied, but has a new problem: it won't be
obvious how to do this, or even that it's possible, just from visual
inspection of the UI.
Because in Twisted-world, moving your cursor to a line and pressing
enter, or just clicking on it with the mouse, is an impossible thought
that will never enter anyone's head.
A user will just see a buffer with the search
results and no hint that they can do anything to go directly from a
search result to a corresponding place in their other document.
Unlike, say, a set of search results in a Windows app that appeared as
blue underlined clickable links or something, which a typical
reasonably computer- and Web-savvy user with no prior experience with
that specific app would immediately recognize as traversable.
And what do you know - my search results /do/ come up as blue
underlined clickable links. The wonders of modern technology . . .
But it's not; when you drop down to a shell and type "grep
somethingorother" it's the shell launching the command.
interpret the input, i.e. by putting it into grep-mode after loading
the file.
So now you have to explicitly put it into this "grep-mode" of yours.
When you insist on doing the search the awkward way, don't be
surprised when it becomes awkward to do it in the way that you
propose.
That's now THREE times that you've misused the word "instantly". First
we had the i-search that "instantly" tells you about an error, up to
several keystrokes later than the error that is;
There are no errors in i-search. There are only search hits, search
misses and end of file.
then the grep mode
that appears instantly, meaning that you have to manually invoke it,
If you insist on using a crufty way to use it, sure.
and finally the grep mode that does something instantly when you hit
down-arrow, meaning that you have to hit another key after down-arrow
for it to happen.
It moves your cursor instantly when you press down arrow - I have not
claimed anything beyond this (and I didn't even claim this).
Perhaps not, but you did assume a uniform distribution of all n-letter
prefixes when you made your ludicrous claims about i-search; under
real-world conditions it will necessarily perform far more poorly and
generate more false positives and require longer queries than you
claimed.
Not so as to be particularly noticable in practice, however.
Wrong again, Bent Dalager. It's quite noticeable. I know from
experience.
Heh. Yeah, you've tried, we know.
Cheers,
