<div dir="ltr">I think the loss of cursor position when hitting `esc`+`m`+`enter` is a bug. I'm able to reproduce it and I've opened an issue for it here: <a href="https://github.com/ipython/ipython/issues/5688">https://github.com/ipython/ipython/issues/5688</a> .<div>

The reason you see this behavior is because<br>
a) custom.js gets executed before there is an IPython.keyboard_manager<br>
b) switching between code and markdown cells actually creates a new cell<br>
<br>
This should do:<br>
<br>
$([IPython.events]).on('app_initialized.NotebookApp', function(){<br>
<div><br>
IPython.keyboard_manager.edit_shortcuts.add_shortcut('ctrl-y', {<br>
help : 'toggle markdown/code',<br>
handler : function (event) {<br>
var cell = IPython.notebook.get_selected_cell();<br>
if (cell.cell_type == 'code') {<br>
</div> var cur = cell.code_mirror.getCursor();<br>
IPython.notebook.command_mode();<br>
IPython.notebook.to_markdown();<br>
IPython.notebook.edit_mode();<br>
cell = IPython.notebook.get_selected_cell();<br>
cell.code_mirror.setCursor(cur);<br>
<div> } else if (cell.cell_type == 'markdown') {<br>
</div> var cur = cell.code_mirror.getCursor();<br>
IPython.notebook.command_mode();<br>
IPython.notebook.to_code();<br>
IPython.notebook.edit_mode();<br>
cell = IPython.notebook.get_selected_cell();<br>
cell.code_mirror.setCursor(cur);<br>
}<br>
return false;<br>
}<br>
});<br>
<br>
});<br>
<br>
