Some keys on your keyboard have two symbols on them. These keys can be used to type alternate characters or to perform secondary functions. The symbol that is shown on the lower part of the key refers to the character that is typed out when the key is pressed. If you press shift and the key, the symbol that is shown on the upper part of the key is typed out. For example, if you press 2, 2 is typed out; if you press Shift + 2, @ is typed out.
The top row of the keyboard is a capacitive touch panel. The fn mechanical key toggles between the keys F1-F12 and keys for multi-media control. Releasing the fn key switches back to the previous mode.
Pressing the fn key and the esc key locks the "mode" of the capacitive touch panel. If the computer restarts, the default mode will be the last mode set by the user before the computer is restarted.
The fn key is also used with selected keys on the keyboard to invoke other secondary functions.
