This is a Linux keyboard driver for the Compaq SDM4540UL 'Internet Keyboard'.
On Linux, there are 9 keys on the keyboard that aren't supported by the kernel, these are:
- The 7 keys in the "blue" area: Search, Bullseye, Mail, Info, Q, e-marketplace, movies/music
- The 2 keys to the right of that: '?' help, person/contacts
This keyboard driver maps those 'dead' keys to function keys:
| Original key name/description | New key mapped to |
|---|---|
| Search | F13 |
| Bullseye/target | F14 |
| Mail/Envelope | F15 |
| Info/'i' | F16 |
| Compaq 'Q' logo | F17 |
| Online marketplace | F18 |
| Movies/Music | F19 |
| Help '?' | F20 |
| Contacts/Person | F21 |
