This key is very important for my pc if I want to see the Bios screen when boot.. F3-This key opens up search page. If I want to search any file or folder or any program, this page is important.. F4- Does nothing.. F5- This function key refresh the desktop or refresh a web page when you open up a web page.. F6 and F7 does nothing.. F8 too does nothing but when system is booting and if I want my system to boot in safe mode and I want to find options of safe mode,etc then I have to keep hitting the F8 button to find that screen F9, F10, F11 and F12 keys does nothing much when I press them. These keys does some function for certain programs. For Suppose if I open IE and press F11 then the IE window will turn into full screen..
