Jupyter-lab

By default, <Esc> — bad idea for the same reason in vim it’s a bad idea.

AND my xkeymap-level keyboard mapping for Esc doesn’t seem to work here.

Default-2 is <C-]> which is impossible because of my custom keyboard layout.

Will be <C-=>.

        {
            "command": "vim:leave-insert-mode",
            "selector": ".jp-NotebookPanel[data-jp-vim-mode='true'] .jp-Notebook.jp-mod-editMode",
            "keys": [
                "Ctrl =",
            ]
        }

(I can’t figure out why ,l etc. don’t work in jupyterlab for this purpose)

vim

(<leader> is ,)

"Insert mode mappings
" Leave insert mode
imap <leader>l <Esc>
imap qj <Esc>

" Write, write and close
imap ,, <Esc>:x<CR>
map ,. :w<CR>

… I will have an unified set of bindings for this someday, I promise.
