jQuery keySelection - Cycling through arbitrary element collections

jQuery keySelection is a lightweight jQuery plugin (3kb) for cycling through arbitrary element collections with arrow keys. Collection members are selectable by keyboard or mouse.

keySelection will always reflect the current dom state, so you can dynamically add elements to the dom and they will be added to the keySelection element collection if they have the required .selection-item class.
