This is the most frustrating thing to date and I can't seem to figure it out!
Lately (and somewhat sporadically) when I use my keyboard shortcut ALT+SPACE on a file in finder (i believe this is called File Search -> Actions -> File Selection) Instead of opening in the nice box where I can apply an alfred workflow to the selected file in Finder, I get a full screen quicklook which I think was introduced as a keyboard shortcut / feature in mavericks.
I've looked everywhere to disable this shortcut so it's not hijacking my alfred. I've also tried changing the shortcut in alfred (see screenshot http://d.pr/NEFH ) but no matter what I change it to, i still can't get alfred to pop up on the file im selecting in Finder (nothing happens)
Hopefully I've explained this somewhat clearly.
TL;DR I can't select a file in finder and use my keyboard shortcut (normally alt+space) to pop up a alfred action window. Instead I just get a full screen quicklook. If i change the keyboard shortcut, it just doesn't do anything.
I'm not 100% sure if I'm changing the right shortcut though because honestly I'm not positive what the feature is named in alfred preferences.
EDIT: I've just updated to 10.9.1 and i'm not sure if its just the reboot, or the update but its currently working, so far so good. ill update if the problem persists but so far that's solved it. Like i said i OP its a bit sporatic
