QUESTION :
My fn+F4 key is the internet browser, and it is set to be internet explore. I want to make it to be chrome, is that possible to do it?
ANSWER :
Don’t know if there’s a laptop specific solution, but check out AutoHotkey, a great software to make any key do whatever you want.
Also, make sure Chrome is your default browser, in case the key launches your default browser, not specifically IE.
Just set Chrome as your default browser. Go to Wrench menu->Options->Basics tab->Default browser: Make Chrome my default browser. Now whenever a web browser needs to be opened (including via the Fn+F4 hotkey), Chrome will automatically be run instead of IE.
