Choosers look like the items in figure 3.4. They are used to select one of a list of possible choices. There are two ways to change the selection. Clicking with the left mouse button brings up the list of choices. Move the mouse to the correct selection and release the button to pick that item, or release the button outside of the menu to keep the original selection. Clicking with the right mouse button advances the selection through the list by one. If the currently selected item is the last element of the list, the selection loops around to the first item.
