not really relevant to your question, but this is a perfect example of why I like to buy keyboards in the format laid down lo these many years ago by IBM when they introduced the venerable Model M. I can use a Filco, a Cherry (G80-3000 or similar), a WASD, a Noppoo (choc pro) or any number of other keyboards including the original M that I still have, and, say, the "Delete" key is within a few mm of where I expect it to be. That means that I also don't have to be a complete snob about keyboards when working on other people's machines; if I'm only going to be there for a few minutes, unless it's a laptop, I don't find myself cussing at the keyboard on it (although anymore they're almost always crappy Dell rubber domes which don't feel nice, but it doesn't impede my ability to find the correct keys without hunting and pecking.)
It may sound cold, but I really recommend buying a keyboard that you like in the bog standard 104-key or tenkeyless layout and just become used to the standard location of the nav block, then you won't ever have this problem again.
BTW, the "right click" key to which I assume that you refer is commonly known as the "menu" key.
