Hi Jarod, All I'm giving some more info regarding what I queried earlier. I hope this will put my query in better light. The missing keys which I've mentioned earlier are basically Remote Controller keys as specified in MHL specifications( www.mhltech.org ). Now, as MHL Specifications are closely related to HDMI(and CEC), hence most probably these 'missing' keys are part of HDMI/CEC specifications too. And hence, my doubt on why these standard keys are missing from <linux/input.h> ? Jarod, You previously mentioned some of the missing keys being similar to Joystick keys. I will really appreciate if you could pin-point the location of joystick keys' existence ? It makes sense to me too if joystick(basically a wired remote control) keys are similar to TV/Monitor Remote Control keys. In case, the keys (like upper-left, upper-right, lower-left, lower-right ) are different from Joystick keys(and hence missing from input.h ), How can I proceed to add these keys ?
