Hi fleetfoot - there are 2 pieces to the grid, the grid lines and the axis lines.

Do you want both of those to toggle on and off with a shortcut key? If so then paste in this script as the command part:

script: /* Toggle grid and axis lines */ moi.grid.display = !moi.grid.display; moi.grid.showXYAxes = moi.grid.display;
