Because saccades are so very fast it may be difficult to see the eye movements as discrete jumps. Smooth pursuit movements are just as their name implies. The eyes move smoothly instead of in jumps. They are called pursuit because this type of eye movement is made when the eyes follow an object. Therefore, to make a pursuit movement, look at your forefinger, at arms length and then move your arm left and right while fixating your finger tip.
Visual scientists have a number of tools at their disposal to record eye moves.
Although I do not get into the specifics of these techniques here is one illustration of eye movement data. At various times reference has been made to fixating ones gaze. The reader will probably find it interesting that even when they fixate a target and attempt to hold their eyes as steady as possible their eyes still undergo very small tremor like movements. These are, in fact, very useful. It has been shown that when there is absolutely no relative motion of an image on the retina that image soon fades and disappears.
