I have problem using combination keys like Ctrl or Alt or Shift. For example when I want to copy selected text I press Ctrl + C,but it isn't working. Or when I want to select all text, I press Ctrl+A, but this also doesn't work. In android studio all combination keys, doesn't work. When I open settings> keyboard> shortcuts , I can't edit shortcuts , because when I enter Ctrl + C for shortcut to copy, ctrl never gets entered , just C.

Those keys are not global. Gnome Terminal for instance uses Shift+Ctrl+C and Shift+Ctrl+V for cut and paste. Use Ctrl+Insert to copy and Shift+Insert to paste.
