Table 3-2. EFI Scan Codes for SIMPLE_INPUT_INTERFACE (continued)<br />
EFI Scan Code Description<br />
0x000b Function 1.<br />
0x000c Function 2.<br />
0x000d Function 3.<br />
0x000e Function 4.<br />
0x000f Function 5.<br />
0x0010 Function 6.<br />
0x0011 Function 7.<br />
0x0012 Function 8.<br />
0x0013 Function 9.<br />
0x0014 Function 10.<br />
0x0015 Function 11. (Newly Proposed)<br />
0x0016 Function 12. (Newly Proposed)<br />
0x0017 Escape.<br />
Table 3- 3 Additional EFI Scan Codes for SIMPLE_INPUT_INTERFACE<br />
0x2000 Shift. (Newly Proposed)<br />
0x4000 Control. (Newly Proposed)<br />
0x8000 Alternate. (Newly Proposed)<br />
The following example shows the new definitions for the EFI Scan Codes, and provides the facility to<br />
export varying modifier states on non-printing characters.<br />
#define SCAN_F11<br />
#define SCAN_F12<br />
0x0015<br />
0x0016<br />
//<br />
// Bit 13 on = Shift<br />
// Bit 14 on = Control<br />
// Bit 15 on = Alt<br />
//<br />
// This allows for interpretation of Shift F10 for<br />
// the scan code by seeing a scan code of 0x2014<br />
// As it allows a Shift-Alt-F10 yielding a scan code of 0xA014<br />
//<br />
// Additionally, a Shift-Tab would be interpreted by reading<br />
// the EFI Scan code as a 0x2000, and a Unicode value of 0x0009.<br />
//<br />
#define SCAN_SHIFT<br />
0x2000<br />
#define SCAN_CONTROL<br />
0x4000<br />
#define SCAN_ALT<br />
0x8000<br />
