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 3-9 shows the keys making up the embedded keypad and Table 3-9 lists them.
| Key name | Keypad function |
| 6 | Clear |
| 7 | 7 |
| 8 | 8 |
| 9 | 9 |
| 0 | / (divide) |
| - | = (equals) |
| U | 4 |
| I | 5 |
| O | 6 |
| P | * (multiply) |
| J | 1 |
| K | 2 |
| L | 3 |
| ; | – (subtract) |
| M | 0 |
| , | NOP |
| . | . (decimal) |
| / | + (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 3-9. The affected keys include certain special character keys: plus and equal sign, right and left brackets, vertical bar and backslash, and straight apostrophe.
