If you press Shift, Control, Command, or Option, the virtual keys’ labels will change to show their alternative versions. In fact, the Keyboard Viewer virtual keyboard is a good way to discover where obscure characters are on the physical keyboard. If you want to click on alternative characters such as the ˚ or ® symbols, you can hold the Option key on your physical keyboard and select the symbol from the virtual keyboard. You can use Caps Lock to hold shifted characters while you select them. But you can only click on one button at once, so can’t select those characters. You can press the Shift or Option keys on the virtual keyboard and see the characters change to their shifted or alternative versions. Now you can click on any key on the virtual keyboard and it will place that character in a currently active document, web browser, or anything else that takes text input. If you want to turn it off, just click the Close button in the top-left corner of the keyboard. You will now see your virtual keyboard appear on the screen.
