To track on a satellite first issue a Slew To when you have found it or clicked on it in TheSky then use the option "Track Satellite" on the telescope tab. See below.

Track on satellite set rates to match
NOTE: Tracking a satellite is not as simple as a planet, comet, or minor planet. It will take one or more slews to get the object in the field then it TheSky will attempt to micro-slew to the object based on the changing rates in RA and DEC.
Note rates are displayed
Satellite tracking dialog
The star symbol in the center represents the center of the field and the smaller circle where the scope is relative to the target. When the two are coincident the object is being precisely tracked!
You can also use a spiral search using Start Search whereby the scope will attempt to find the object if it is no where in the field. If the object is in the field but offset from center you can mouse click inside the square box and the object will be offset from the current position in the opposite direction. Takes practice! This way you can manually center the satellite provided it is in your field. If not try to search for it a second time and make sure you are setting the rates to match the bird. Good luck!
Before trying to nail a fast moving bird first make the tracking work with a Geosynchronous orbit satellite. Why? Because they hardly move at all! These are quite easy and fun. In fact you can actually just turn the tracking off completely and these satellites will remain in the field. Even in very small CCD fields. See below image.
