If you have "Help" instead of "Ins", replace it with Overgod-tier. Keep pressing it, it will come.
OC, feel free to share.
EDIT; Home is now G-od tier. I didn't know it would go to the beginning of a line, I always used macros "lol".
F9-F12 are useful when you're debugging code in Visual Studio.
I sometimes use F6 to jump to my browser's address bar.
Can't imagine any uses for F7 or F8 though. And all the times I've opened a help screen with F1 have been on accident.
My main gripe with function keys on laptops is they're tiny and easy to mix up, especially since they have large brightness, volume, etc. icons on them while the function key number is a tiny label that's barely visible.
