The Random Seed control contains the value used to seed the random number generator. Given the same seed, a random number generator will always produce the same results. Change the seed if the results from the randomizer are not satisfying.

This control is used to smooth the overall randomness of the shake. The higher the value is set, the smoother the motion will appear. A value of zero will generate completely random results, with no smoothing applied.

This checkbox is used to Unlock the X and Y axis, revealing independent slider controls for each axis.

This control is used to determine the overall strength of the shake. The low values represent the lowest value that can be generated by the randomizer and the high values represent the highest values. To create a shake that moves a center crosshair anywhere within the image, set the low to 0.0 and the high to 1.0. To restrict the motion to a smaller shake in the bottom right corner of the image, set the Min to 0.70 and the Max to 0.90.

Create a new flow and add a Text tool. Type something in the Text tool and view it in the large display. Add a shake modifier by selecting Modify With>Shake Position from the context menu for the Text Center control.

Switch to the Modifier tab and set the smoothing to 5.0. Set the Low to 0.1 and the High to 0.9. Go to frame 0 and add a Bezier spline to both the Low and the High controls.

Advance to frame 90 and set the Low to 0.45 and the High to 0.55. Render out a preview and view the results. The text should start out by flying all over the screen and then tighten in toward the center of the screen.
