If you mean creating the graphics for a slider, there are tutorials out there. I wrote one for Community MX, where the grpahics went over to Flash Catalyst for builiding in functionality.
FW is not capable of creating the functionality of a slider. Look into Flash, jQuery or possibly Adobe Edge for that kind of thing.
Darrell Heath created a whole kit of sliders using Fireworks. You can find them on his website at heathrowe.com
