Is the 3D viewer Jog function (ctrl + mouse click) limited by the grid

Is the 3D viewer Jog function (ctrl + mouse click) limited by the grid size? I can manually (with keyboard) jog to the full size of my machine. I can not use the 3D viewer JOG function to move to any geometry that falls out side the 3D view grid. Is there a way to set the 3D grid to show the XYZ origin in the lower left (or to match a given machine) of the grid rather than the center? or a way to display a outline/overlay that represented the actual machine work area size?

Just show a larger grid from the top tool bar.
