Mate에서 Shift를 사용한 키보드 단축키

Mate를 사용하여 Fedora 21을 설치했습니다. 단축키 Ctrl+ Alt+ Shift+ Up(창을 특정 데스크탑으로 이동하는 데 사용됨)를 바인딩하려고 하면 이미 Ctrl+ Alt+를 사용하여 Up전환하고 있다는 메시지가 나타납니다. 왜 Shift키를 무시하는지 이해가 안 돼요 .

또한 JetBrains IDE에서 몇 가지 이상한 동작을 발견했습니다(그러나 Debian 배포판의 동일한 기본 구성은 잘 작동합니다). 예를 들어 Alt++는 행을 위/아래로 이동 Shift하지 않습니다 . Up어떤 제안이라도 감사하겠습니다.
