where are the function keys on my HP laptop？

I'm looking for function keys so that I can use it on shortcuts and commands.

That depends on what model of HP laptop you have. Until you tell me that, the best answer I can give is "On the keyboard, probably near the top."
Often there's a function modifier key, like the Shift or Ctrl key. Press that key and 7 and you get function-7.
Please post your model, preferably with a link to a product page with a good view of the keyboard.
