How do I hide XYZ in Sketchup?

SketchUp enables you to hide the drawing axes in two ways:

1. Context-click an open area on an axis and select Hide from the menu that appears.
2. Select View > Axes from the menu bar. When a check mark appears next to the Axes menu item, selecting this option clears the Axes menu item and the axes are hidden from view.
