This wiki is a place to share snippets that enhance the usability of the vim - IPython integration, but aren't so general that they are part of the binding.

Move around in Insert mode with Ctrl-X

require(['codemirror/keymap/vim'], function() {
  // Use Ctrl-h/l/j/k to move around in Insert mode
  CodeMirror.Vim.map("<C-h>", "<Esc>i", "insert");
  CodeMirror.Vim.map("<C-l>", "<Esc>lli", "insert");
  CodeMirror.Vim.map("<C-j>", "<Esc>ji", "insert");
  CodeMirror.Vim.map("<C-k>", "<Esc>ki", "insert");

  // Use Ctrl-h/l/j/k to move around in Normal mode
  // otherwise it would trigger browser shortcuts
  CodeMirror.Vim.map("<C-h>", "h", "normal");
  CodeMirror.Vim.map("<C-l>", "l", "normal");
  CodeMirror.Vim.map("<C-j>", "j", "normal");
  CodeMirror.Vim.map("<C-k>", "k", "normal");
});

Selecting all

require(['codemirror/keymap/vim'], function() {
   CodeMirror.Vim.map("<C-a>", "ggVG", "normal");
});

Adding custom actions

require(['codemirror/keymap/vim'], function() {
  // a
  CodeMirror.Vim.defineAction("hello", function(){console.log("hello")});
  // 'a' is the key you map the action to
  CodeMirror.Vim.mapCommand("a", "action", "hello", {}, {context: "normal"}); 
});

Calling a Jupyter shortcut

require(['base/js/namespace'], function(ns) {
    ns.keyboard_manager.actions.call('jupyter-notebook:run-cell-and-insert-below');
});
