Vim incompatibility inserts line breaks

[bulletmark]

Describe the bug

When you press <CR> in vim in normal mode then the cursor simply moves from whatever position it is in a line to the start of the next line. In the marimo editor, it inserts a <CR> so it breaks the line (although the editor stays in vim normal mode). I must do this very frequently because I keep inserting line breaks all over my code. I've been using vi/vim pretty much daily for 35+ years so would be hard for me to adapt to this incompatibility!
