I love the K780, however it still has to improve a lot of things in order to get close to the perfect keyboard. Probably the thing that annoys me the most is those annoyingly shaped standard arrows, so I would like to use the Numpad Arrows instead. But, if you use the Shift + Arrow combination to highlight something, it simply doesn't work, at least not on my configurations: I use Ubuntu 18.04 right now --- does it work on Windows? (I will create a Windows VM later to see if it works, but does the key go through Ubuntu before reaching the VM?)
So... is there a way to fix this on Ubuntu? Maybe I could preconfirue it on a Windows machine and then switch back to Ubuntu?
