Yes, you've got that right FS, but it works very efficiently...
Further to that, simply pressing Ctrl + Alt + / gives a full review of all the extra functions on the C720 Keyboard... There is an explanatory note on the image, which disappears when the combination of ~ Ctrl + Shift are pressed, Alt + Shift are used together or even a Ctrl + Alt combination... The same applies using those keys singly...
Pressing The Esc key, will clear the screen...
I find the C720 to be an exceptionally neat and practical little machine... Having said that, I personally still have and use full computerized systems for daily needs... My Chromebook was purchased mainly for training purposes...
Hope that helps somewhat...
