odd question regarding adb function keys..

[chelseayr]

how many function keys was actually supported in software? or was f15 generally the highest as far as pre-usb went?

I did thoughtfully try have a quick look at the macos9-compatible quickey documentation still available on their website but not surprisingly it actually didn't even mention much in the first place .. and a quick peruse of the web didn't give much so I decided it couldn't hurt to just ask here for now nevertheless

I suppose it depends on the OS and drivers and API.

There were USB keyboards with an F16.

    kgestUSBProF16ANSIKbd    = 34,        /* USB Pro Keyboard w/ F16 key Domestic (ANSI) Keyboard */
    kprodUSBProF16ANSIKbd    = 0x20B,
    kgestUSBProF16ISOKbd    = 35,        /* USB Pro Keyboard w/ F16 key International (ISO) Keyboard */
    kprodUSBProF16ISOKbd    = 0x20C,
    kgestUSBProF16JISKbd    = 36,    /* USB Pro Keyboard w/ F16 key Japanese (JIS) Keyboard */
    kprodUSBProF16JISKbd    = 0x20D

For Mac OS X, starting from IOUSBFamily-198.4.3, the USB key code 0x6a was translated to ADB key code 0x6b. https://github.com/apple-oss-distri....4/AppleUSBKeyboard/Classes/Cosmo_USB2ADB.cpp

    0x69,    // 68  F13 on Andy keyboards
    0x6b,    // 69  F14 on Andy keyboards
    0x71,    // 6a  F15 on Andy keyboards
#if __AppleUSBKeyboard_Darwin_1_3__
    0x0,    // 6b
#else
    0x6a,    // 6b  F16
#endif
    0x0,    // 6c
    0x0,    // 6d
    0x0,    // 6e
    0x0,    // 6f

AppleUSBKeyboard has since been removed from Apple Open Source.

@joevt mm interesting .. anyhow I was also curious about using higher function keys for certain aux inputs-related devices as the os wouldn't had recognized such keypresses itself anyhow
