Vim Esc to go to normal mode doesn't work



When I press Esc instead of going to normal mode, the editor loses focus and I can’t type anything.

Has anyone encountered this problem before?

I’m using Chrome on Windows.


Are there any related errors in browser console?
Does this happen always or only sometimes?


There are no related errors in the browser console.

This happens all the time.



Maybe there is a chrome extension capturing keys before they reach cloud9. I think vimium was causing something similar.
Try disabling them or opening in incognito mode.
