When using a PC keyboard to control your Apple Macintosh computer, some of the keys available on a Mac keyboard will not be labeled on the PC keyboard. Mac OSX will still recognize the keyboard shortcuts programmed into the operating system, but you will have to push different keys to access the shortcuts. Knowing which keys on a PC keyboard function as Mac keys will help you save time when using keyboard shortcuts.
Press "Alt" on your PC keyboard when you need to "Option Click." Your computer will detect an "Option Click" event when you press and hold "Alt" while clicking the mouse.
Press "Alt" on your PC keyboard whenever you need to perform a keyboard shortcut that requires you to press the "Option" key on a Mac keyboard. The "Alt" key is the PC equivalent of the "Option" key on the Mac.
Press the "Windows" key on your keyboard whenever you need to perform a keyboard shortcut that requires you to press the "Apple" key. The "Windows" key on your PC keyboard is the equivalent of the "Apple" key on a Mac. The "Apple" key is also called the "Command" key.
Some PC keyboards have a “Function Lock” key that activates the “F-number” keys at the top of the keyboard. If you are pressing one of the function keys and it is not performing the desired action, press the “F-lock” or “Function Lock” key to activate the function keys and try the function key again. If you have a mouse with two buttons, right-clicking performs the same function as “Option Clicking.”
