A certain group of alphanumeric keys can also function as an embedded keypad. The user selects this mode by using the Fn key or the Num Lock key. Figure 3-7 shows the keys making up the embedded keypad and Table 3-10 lists them.
| Key name | Keypad function | Key name | Keypad function |
| 6 | Clear | P | * (multiply) |
| 7 | 7 | J | 1 |
| 8 | 8 | K | 2 |
| 9 | 9 | L | 3 |
| 0 | / (divide) | ; | – (subtract) |
| - | = (equals) | M | 0 |
| U | 4 | , | NOP |
| I | 5 | . | . (decimal) |
| O | 6 | / | + (add) |
When the embedded keypad is made active by the Num Lock key, the other alphanumeric keys have no operation (NOP), as shown in Figure 3-7. The affected keys include certain special character keys: plus and equal sign, right and left brackets, vertical bar and backslash, and straight apostrophe.
