Yeah...what Tom said. Dell in their infinite wisdom made a change to some of their laptops where you had to press the FN key when you want to use F1, F2, etc functions. And of course, the F2 key, which is what most programs use as edit, just happened to be the wireless toggle. That one pissed my off for a while.
The newer laptops we have are now back to normal ( i.e. you want F2, press F2 ).
