Look for a key labeled fn or Fn. On my keyboard it is to the right of the left Ctrl key, but it might be different on another laptop.
Press Fn+F2 if you want to edit a cell, Fn+F1 for Help, etc.
Also look for a key with a lock symbol on it. On my keyboard, it is the Esc key, but again, it might be different.
Pressing Fn+lock key "locks" the Fn key, so that F2 is now Edit and Fn+F2 lowers the volume.
Pressing Fn+lock key again "unlocks" the Fn key.
