What is the expected output? What do you see instead?
The h, j, k, and l keys would perform the same actions as the left, down, up, and right arrow keys, 
respectively, when pressed in conjunction with a modifier key (suggested: the control key).

What version of the product are you using? On what operating system?
2.0.0.1447, 10.5.6

Please provide any additional information below.
Beyond Vim, many Gmail users will be accustomed to "jk" keyboard navigation. It keeps your hands 
on the keyboard at home row (with a QWERTY keyboard). See Launchbar for an example.

I've started working on this.  I get that j/k should move up and down the results
list.  Sean (or others), what do you think that h and l should do?  Move the text
cursor in the entered string, or (de)pivot from results?  I'm thinking that latter
would be more useful, but I'm not sure.  Thoughts?

That's excellent. Thank you. I think it would be most useful if h and l behaved like the left and right arrow keys 
respectively. This would be particularly useful when drilling 'shallower' or 'deeper' through folder structure or 
through actions for a given result. Is that what you mean by (de)pivot the results?

Yes.  Specifically, say you've pivoted into a folder and entered some further text to
search in that folder.  Now say you press ctrl-h.  Should that move the cursor to the
left in the text entered (just like the left arrow), or immediately pivot out of that
folder and back into the higher level search?

I would have the vi keys mimic the arrow keys exactly. Keep them consistent please.

I actaully have a patch for this, but in the process of writing it, I thought of an
IMHO better solution.  Instead of modifying the code of QSB, the user(s) who want
this feature can modify their system-wide keybindings to map ctrl-h,j,k,l to left,
down, up, right movement.  In order to do this, add these lines to the file
~/Library/KeyBindings/DefaultKeyBindings.dict, creating the file and containing
folder if it doesn't exist:

	"^h" = "moveLeft:";
	"^j" = "moveDown:";
	"^k" = "moveUp:";
	"^l" = "moveRight:";

These lines must be enclosed in curly braces.  If you create the file, be sure to do
so; if it already exists there will already be a set of braces.  (For more info:
http://www.hcs.harvard.edu/~jrus/Site/Cocoa%20Text%20System.html)

The only downside is that this change will be system-wide, and some users might not
want that.  But it seems the request for vim-style keys is uncommon enough (receiving
only two stars on here, including mine) that I don't think we should add special code
to QSB to accomplish that.  I'll push the patch to Rietveld if devs think it is worth
including anyway.
