On my Lenovo IdeaPad Yoga 2 Pro on Windows, there is a function available Fn+F6  that should turn the touchpad on and off (I would like to map the correct key to the script here on askubuntu).But on Linux, it doesn't work.How can I find out the event keycode that it emmits when I press this combination?I tried showkey -a, showkey -k and xev which both shows most keys codes when pressed, but at Fn+F6 they stay quiet. The other Fn+F1-F5 show output, only F6 doesn't, although it works on Windows. What other alternatives are there to xev and showkey?The only hint i found so far is:grep TOUCHPAD /usr/include/linux/input.h#define KEY_TOUCHPAD_TOGGLE 0x212   /* Request switch touchpad on or off */#define KEY_TOUCHPAD_ON     0x213#define KEY_TOUCHPAD_OFF    0x214source: comment in https://askubuntu.com/a/270428/34298 with link to this articleMaybe someone has an idea?
