On my keyboard i have some userful key like one for go to homepage, one for launch music app and others, most of them works, other not. I'm interested at "calc" and "file" key(i think the most userful), but they don't work.


Probably you need to add shortcuts for them. In System Settings >Keyboard you'll find shortcuts for variety of functions and you can change keys to use these functions.

If you want to add a custom shortcut, go to the last tab where you can create your own shortcut - you define terminal command that is performed on event of clicking for example your calc key (maybe open calculator or libre office calc)

  • The problem is that i can assign all this keys because they are like the SHIFT button :( – mac12 Dec 27 '16 at 19:29
  • It doesn't matter if you use these keys with shift or not. When mapping key to command you can click shift+your key and it saves event of clicking both keys at once. – Dysproz Dec 27 '16 at 19:45
  • The problem is that i can't map these keys, when assignign if i click only this keys commands say "disabled", but for example shift+Calc is accepted(another key+calc). So at the end, i can't use these buttons. – mac12 Dec 27 '16 at 20:53
  • It seems that it's the same bug as it is with Print Screen. You can't assign this key separately, but with other key like shift. – Dysproz Dec 28 '16 at 11:21
