You are very welcome. I'm glad that some of the Fn-Fx key combinations work.

There might be a way of getting the Fn-Fx key combinations for turning on/off your wireless card and the touchpad. I don't know what desktop you're using, but apparently KDE has an application for mapping keys, of which I know nothing.

I know in the past I have used xmodmap, and there are tutorials/how-to web sites one can find in a search that can be very helpful. It can be used to map multimedia keys to events, or as in your case, map the Fn-Fx key combination to enable/disable wireless. I was reading through some sites and find xmodmap can be very useful. Its use is also very specific to each system on which it runs, therefor there is no direct and simple manner to provide instructions on how to map your keys to do what you need. It will take some studying, then of course more time to get it to work on your system.

Oh,yes,I have used xev to catch Fn Code，but no response.It doesn't matter,I'll go to read some Xmodmap relative article and try to use Win key to take place of Fn key to make others work. Maybe I have to learn write some bash scripts.
, Thank you for you warm heart,devwatchdog.
