No worries!
If you can, just open the link and press shift+c and see if the content change to “MODAL CONTENT”
Thank you!
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.
