System BIOS Boot Keys for Laptops/Desktop PCs

Here is my list of Laptop and Desktop System Boots Codes for various vendors.  It's great if you're a technology like me and you're trying to remember what code to use for a particular brand or model of computer. Note, not all keys will work as some models have different key combinations to others.
