   6 At work I’m using the Dell Latidude E5500 notebook, running on Debian
   7 testing.  Today, I had some issues with Xorg which could not detect my
   8 keyboard and mouse, so I tried to do the Magic SysRq tricks (you can
   9 read about it at [Wikipedia][1]).  Unfortunatley, to press `SysRq` (on
  10 `F10`), I had to use the `Fn` key, so if I pressed e.&nbsp;g.
  11 `Alt`+`Fn`+`SysRq`+`U`, the `U` was detected as `keypad 4` because of
  12 the `Fn` key.  Luckily, it works as intended if you release the `Fn` key
  13 after having pressed `Fn`+`SysRq`, so to remount all mounted filesystems
  14 in read-only mode, you would actually hold `Alt`, hold `Fn`, hold
  15 `SysRq`, release `Fn`, press `U`.

  17 Never thought notebook keyboards were so smart :-)
