问题 So I've just migrated to Fedora Linux and ran over this problem when using my Idea. I have a notebook (no numpad) and I previously used the very same Idea (Ultimate, latest) with Win10 on this very same notebook and did not experience this. I use default English layout. In the lower row of QWERTY, to the right there is / button which is also ? with shift. It works as expected anywhere else, but in Idea, when I use it as a CTRL + / shortcut it actually treats it as a Ctrl + . Thus, instead of
