When I want to work in a kernel of my Jupiter notebook open in Visual Studio, I have to type "I" to write something. If I don't do that and I start to write my code, nothing happened and sometimes it's clear the content of my kernel. Do you know why I have to type "I" and why can I no directly write my code?

The problem was that Visual Studio Code was bound to vim. After uninstalling it, the problem was solved.
