Occasionally,

you will come across a menu option that acts as a toggle, which is to say the option
represents some feature that can be turned on, or turned off. If you open the View menu in WordPad,
for instance, you might notice that some of its items have check marks next to them, as in Figure 2-5.
Choosing an option that has a check mark next to it turns the toggle off and removes the check mark. If
you choose the currently checked Toolbar option in WordPad’s View menu, for example, the Toolbar
option is turned off, which makes the toolbar disappear from the screen. To turn the toolbar back on,
choose View › Toolbar again to switch that option back on.
