Description
originui toggles the origin tool on and off.
originui on activates the origin tool.

The originui tool allows for interactive modification of the origin of a displayed map projection. A dot marker appears on the map at the location of the current origin. This dot can be moved using the mouse or keyboard, and the map can be reprojected with the location of the dot as the new origin.
Controls
A single-click and drag moves the dot marker. A double-click on the dot marker reprojects the map with the dot location as the new origin. An extend-click moves the dot marker in the x or y direction only, depending on the direction of greatest mouse movement. Alternate-click exits the origin tool.
The following keyboard interaction is enabled if the figure containing the map axes is made the active window.
The n, s, e, and w keys move the dot marker north (up), south (down), east (right), and west (left) by one degree per keystroke. N, S, E, W keys move the dot marker ten degrees per keystroke in the same directions. Pressing the Return key reprojects the map with the dot location as the new origin. Pressing the Enter key reprojects the map with the new origin and exits the origin tool. Pressing the Esc or Delete keys exits the origin tool.
