Maybe he meant Mat posted it somewhere,and that Gem read it.
Then he twisted his sentence a bit.

Yes,very shocking to see Mat flame on someone.
They're probably stationary screws - If you look at the Navigator and then that remote, you'll see that there are two (what I believe to be) screws above the first two buttons and below the bottom two (if you consider the eighth hole a button.)
Still considered inspiration, even if he didn't copy it exactly.
What if the navigator wasn't SUPPOSED to be a Navigator, and in its original purpose it needed 8 buttons.
Then someone used parts of it (and other stuff) to cobble together the Navigator as we know it.
