I have this [code](http://jsfiddle.net/fCAAY/68/)

I use jkey to simplify the usage on detecting which key is pressed.

**Question**
What i want is when any other except up arrow key is pressed set the value of `count` to `-1` and if up arrow key is pressed do it just like in the code.

Is there a way out by using the jKey plugin ?
if not then how do i do it with normal jquery
