Ctrl+Shift+←/→/ doesn't work, Shift+←/→/ at the end of line doesn't work, no quick access to console, so I will continue to use mcedit from mc instead.
As someone who used mcedit for ~20 years now and vim for ~1 year I still feel sometimes I'm faster in mc+mcedit for both code edit and navigation. It's slowly moving towards vim(neovim actually) with the whole copilot autocomplete stuff that when used properly can speed things up a lot.
