Because this letter is one of the shortcut letters, your script captures it anywhere on the page, and not just in the items pane.

When I go to the search pane at the top of the page, I can't type any word with "w" in it.

Same here.

Error console shows the same warning 8 times in a row each time W is pressed:
The 'charCode' property of a keydown event should not be used. The value is meaningless.

Same thing happens in the old version of this script, but it seems easier to escape and be able to type a W. If you click All Items, or something in the left pane, you can then go and search. But if you've clicked on an article, W can't be typed in search.

Aha... you can type a Capital W (q does the same thing too), and it works fine. I guess it's looking only for a lowercase w or q.

Here's a quick fix, since I see that the author of this script is not that responsive.

Edit the script's source (click "Edit" in the Greasemonkey app while pointing on the script), and do a search for if (key_code == 'q').

You will see it towards the end of the script, along with if (key_code == 'w') a few lines below it.

Change it to whatever you want. Mine were changed to ( and ).

While we're at it, I also disabled the Mark above as read, because for me it's completely useless.
I read all my feeds, and I always click a certain feed, and then read it bottom to top. Therefore I always need to mark only the items below where I'm pointing.

To disable this button, look for the line:
viewer_ctrls.appendChild(mark_above_btn);
And add "//" in front of it, to make it look like this:
//viewer_ctrls.appendChild(mark_above_btn);
