I just installed Fast Dial and think it's a great idea

But is there away to cancel a button that I assigned as a short cut key to activate fast dial.

I tried to assign f5 as my shortcut key, clicking the shortcut key slot, and typing f5. I subsequently typed "enter" just as I would after typing a google search.

Now whenever I typed "enter" be it when I'm typing a website in the address bar, or when I'm trying to log on facebook, it directs me to the fast dial page.

I tried assigning the shortcut key to another button (being f6), and now all f5, f6 and "enter" direct me to fast dial

this is very inconvenient, since I dont want "enter" to direct me to fast dial.

I tried clicking default, but it's not working even when i restart firefox

Please help, i just want to cancel "enter" as a shortcut key
