I will be honest and admit that while I'm on Linux and all, I don't know what to do with what you sent me-- I could install it with NPM, but I don't know how to use it ^^; How do I run this?
Oh that's what they meant by "live editor", somehow I didn't understand ahah.
Anyway, I get MODAL CONTENT with shift+c, whether I use the left shift or the right shift. I tried other shortcuts (such as replacing shift+c in the live editor by alt+c, shift+x, etc) and can confirm that I got MODAL CONTENT and issue list when expected.
