The inner key on the left, identified by one horizontal bar, is subnamed F2. The inner key on the right, identified by one vertical bar, is subnamed F3. The outer key on the right, identified by three vertical bars, is subnamed F4. The keys in the middle form a five-way directional pad:

  - The short, thin keys that form a square around it are subnamed Left, Right, Up, and Down.
- The five Thumb keys on the front, from left to right, are subnamed: Left, Up, Home, Down, Right. The Home key is identified by a vertical bar in the middle.
