Got this laptop almost a year ago, and it took me a while to figure out I have to push "function" AND "F11" to toggle in and out of full screen; my last laptop, you just had to push "F11". However, sometime between today and yesterday, it suddenly stopped toggling. I finally figured out that if I push the "Windows" button (command button?) and "F11", it works. Why would it suddenly change the function of the buttons like that? It doesn't really matter as long as A button works, but it's annoying that it would just change like that out of nowhere. And "function" made more sense, since the key serves both as a "fast forward" key and an "F11" key, so "function" is logically what would switch between functions.
