problem with keyboard

[xieu90]

hi everyone
i bought a new laptop, lenovo SL500
everything sofar is ok
except one thing
volume up, down, mute, and most important , there is a key, which is like the right button of mouse,(i will call it from now on X )(it is normally between CTRL and ALT GR or between CTRL and windows key or space)

those key wont do a thing
in hotkey menu i pressed mute, volume down,up but it looks like they wont work, the X one works hardwarely because in vista i did reply and opened the menu.
so what should i do now ?

Keyboard shortcuts are customized through gconf-editor, although I suggest reading up on this quite a bit before you just start poking at things with gconf-editor.

this is somehow like register or regedit in windows , isnt it ?
so where can i read thing about gconf editor?
